Mr. Chief Justice Stone
delivered the opinion of the Court.
Of the several questions raised by this record only one requires our attention: Whether under the Fair Labor Standards Act, 52 Stat. 1060, 29 U. S. C. § 201, et seq., the Administrator of the Wage and Hour Division of the Department of Labor has authority to delegate his statutory power to sign and issue a subpoena duces tecum.
On application of respondent, pursuant to § 9 of the Act, the District Court for Eastern Louisiana ordered petitioner to show cause why it should not be compelled to obey a subpoena duces tecum. The subpoena, issued by a regional director of the Wage and Hour Division, [359]*359commanded the production at New Orleans, Louisiana, before a specified officer of the Division, of all books, papers, and records showing for a period of eighteen months after the effective date of the Wage and Hour provisions of the Act the hours worked by employees each working day and each working week, all wages paid, all purchases made and shipments received, and all goods sold, shipped, delivered, transported, or offered for sale at petitioner’s Shreveport, Louisiana, plant.
The District Court denied petitioner’s motion to dismiss the proceeding for want of jurisdiction, and ordered it to produce the demanded books, papers, and records relating to wages and hours, but left undecided, until again presented to the court in the course of investigation, the further question whether the books and records relating to purchases and shipments specified in the subpoena should be produced. The Court of Appeals for the Fifth Circuit affirmed, 119 F. 2d 209, specifically ruling that the subpoena was validly issued and that the court had jurisdiction to enforce it. We granted certiorari, 314 U. S. 592, on a petition which presented as a ground for reversal the want of authority in the regional director to issue the subpoena and, as a reason for allowing the writ, the conflict on this point of the decision below with that of the Circuit Court of Appeals for the First Circuit in Lowell Sun Co. v. Fleming, 120 F. 2d 213, certiorari granted, 314 U. S. 599.
By § 11 of the Act the Administrator and his designated representatives are authorized to conduct investigations which he may deem necessary “to determine whether any person has violated any provision of this Act, or which may aid in the enforcement of the provisions of this Act.” The Act does not define the Administrator’s power to issue subpoenas or specifically authorize him to delegate it to others. But, for the purposes of any-hearing or investigation, § 9 of the Act makes applicable to the powers and [360]*360duties of the Administrator, the Chief of the Children’s Bureau,1 and the industry committees,2 the subpoena provisions of §§ 9 and 10 of the Federal Trade Commission Act. 15 U. S. C. §§ 49 and 50. The Administrator is thus given all the powers with respect to subpoenas which are conferred upon the Federal Trade Commission, and no more. Under § 9 of the Trade Commission Act the Commission may require the attendance and testimony of witnesses, and production of documents by subpoena; and any members of the Commission may sign the subpoenas. The Commission may apply to any district court within whose jurisdiction an investigation is carried on for an order compelling compliance with a subpoena.
The Administrator argues that he is given authority to delegate to regional directors the signing and issuance of subpoenas by § 4 (c) of the present Act, and that, in any case, this authority is to be implied from the structure of the Act and the nature of the duties which are imposed upon him. Section 4 (c) provides: “The principal office of the Administrator shall be in the District of Columbia, but he or his duly authorized representative may exercise any or all of his powers in any place.” On its face this seems no more than a definition of the geographical or territorial jurisdiction of the Administrator and his representatives. The designation of the District of Columbia as the location of the Administrator’s principal office is qualified by the provision that either the Administrator or his representative may exercise “his powers” in “any place.” Only if such is its meaning does § 4 (c) comport with the structure and related provisions of the Act.
[361]*361If, as the Administrator contends, the section is to be read as authorizing delegation of the subpoena power, that authority is without limitation. He may confer the power on any employee appointed under § 4 (b), whom “he deems necessary to carry out his functions and duties,” or even on those who render the voluntary and uncompensated service which he may accept under that section. Moreover, if so read, § 4 (c) likewise gives the Administrator unrestricted authority to delegate every other power which he possesses, and would render meaningless and unnecessary the provisions of § 11 authorizing the Administrator to delegate his power of investigation to designated representatives.
If such is the meaning of the Act, he could delegate at will his duty to report periodically to Congress (§4 (d)), to appoint industry committees and their chairmen, to fix their compensation and prescribe their procedure ( § 5), to approve or disapprove their reports by orders whose findings of fact, if supported by substantial evidence, are conclusive (§ 10), to define certain terms used in the Act (§ 13), to provide by regulations or orders for the employment of learners and handicapped workers (§ 14), as well as other duties. A construction of the Act which would thus permit the Administrator to delegate all his duties, including those involving administrative judgment and discretion which the Act has in terms given only to him, can hardly be accepted unless plainly required by its words.
The Administrator seeks to meet this difficulty by construing § 4 (c) as authorizing the delegation of some but not all of his administrative functions. But we cannot read “any or all” as meaning “some.” And in any case if only some functions can be delegated, we are afforded no legislative guide for determining which may and which may not be delegated. We think that the words of the section, read in their statutory setting, make it reasonably [362]*362plain that its only function is to provide that the Administrator and his representatives may exercise either within or without the District of Columbia such powers as each possesses. This construction is fully supported by the .legislative history of § 4 (c).3
[363]*363The Administrator also urges that his authority to delegate the subpoena power is to be inferred from the nature of his duties and from the fact that under § 11 he may through designated representatives gather data and make investigations authorized by the Act. He points to the wide range of duties imposed upon him, the vast extent of his territorial jurisdiction, and the large number of investigations required for the enforcement of the Act. From this he argues that Congress must have intended that he should be permitted to delegate his authority to’ sign and issue subpoenas.

The Commission may apply to any district court within whose jurisdiction an investigation is carried on for an order compelling compliance with a subpoena.
The Administrator argues that he is given authority to delegate to regional directors the signing and issuance of subpoenas by § 4 (c) of the present Act, and that, in any case, this authority is to be implied from the structure of the Act and the nature of the duties which are imposed upon him. Section 4 (c) provides: “The principal office of the Administrator shall be in the District of Columbia, but he or his duly authorized representative may exercise any or all of his powers in any place.” On its face this seems no more than a definition of the geographical or territorial jurisdiction of the Administrator and his representatives. The designation of the District of Columbia as the location of the Administrator’s principal office is qualified by the provision that either the Administrator or his representative may exercise “his powers” in “any place.” Only if such is its meaning does § 4 (c) comport with the structure and related provisions of the Act.
[361]*361If, as the Administrator contends, the section is to be read as authorizing delegation of the subpoena power, that authority is without limitation. He may confer the power on any employee appointed under § 4 (b), whom “he deems necessary to carry out his functions and duties,” or even on those who render the voluntary and uncompensated service which he may accept under that section. Moreover, if so read, § 4 (c) likewise gives the Administrator unrestricted authority to delegate every other power which he possesses, and would render meaningless and unnecessary the provisions of § 11 authorizing the Administrator to delegate his power of investigation to designated representatives.

A construction of the Act which would thus permit the Administrator to delegate all his duties, including those involving administrative judgment and discretion which the Act has in terms given only to him, can hardly be accepted unless plainly required by its words.
The Administrator seeks to meet this difficulty by construing § 4 (c) as authorizing the delegation of some but not all of his administrative functions. But we cannot read “any or all” as meaning “some.” And in any case if only some functions can be delegated, we are afforded no legislative guide for determining which may and which may not be delegated. We think that the words of the section, read in their statutory setting, make it reasonably [362]*362plain that its only function is to provide that the Administrator and his representatives may exercise either within or without the District of Columbia such powers as each possesses. This construction is fully supported by the .legislative history of § 4 (c).3
[363]*363The Administrator also urges that his authority to delegate the subpoena power is to be inferred from the nature of his duties and from the fact that under § 11 he may through designated representatives gather data and make investigations authorized by the Act. He points to the wide range of duties imposed upon him, the vast extent of his territorial jurisdiction, and the large number of investigations required for the enforcement of the Act. From this he argues that Congress must have intended that he should be permitted to delegate his authority to’ sign and issue subpoenas. But this argument loses force when examined in the light of related provisions of the Act and of the actual course of Congressional legislation in this field.
Unlimited authority of an administrative officer to delegate the exercise of the subpoena power is not lightly to be inferred. It is a power capable of oppressive use, especially when it may be indiscriminately delegated and the subpoena is not returnable before a judicial officer. Under the present Act, the subpoena may, as in this case, be used to compel production at a distant place of practically all of the books and records of a manufacturing business, covering considerable periods of time. True, there can be no penalty incurred for contempt before there is a judicial order of enforcement. But the subpoena is in form an official command, and even though improvidently issued it has some coercive tendency, either because of ignorance of their rights on the part of those whom it purports to command or their natural respect for [364]*364what appears to be an official command, or because of their reluctance to test the subpoena’s validity by litigation. All these are cogent reasons for inferring an intention of Congress not to give unrestricted authority to delegate the subpoena power which it has in terms granted only to the responsible head of the agency.
The subpoena power differs materially in these respects from the power to gather data and make investigations which is expressly made delegable by § 11. Without the subpoena that power is, in effect, a power of inspection at the employer’s place of business to be exercised only on his consent. It is much less burdensome than the requirement of his selection of great numbers of books and papers and their production at other places. Because of these differences, it seems to us fairly inferable that the grant of authority to delegate the power of inspection, and the omission of authority to delegate the subpoena power, show a legislative intention to withhold the latter. Moreover, if a subpoena power in the regional directors were to be implied from their delegated authority to investigate, we should have to say that Congress had no occasion expressly to grant the subpoena power to the Administrator, who also has the power to investigate, and that the grant to him was superfluous and without meaning or purpose.
The entire history of the legislation controlling the use of subpoenas by administrative officers indicates a Congressional purpose not to authorize by implication the delegation of the subpoena power. The Interstate Commerce Act,4 the National Labor Relations Act,5 and the Federal Trade Commission Act,6 whose subpoena provisions were adopted by the present Act and by the Pack[365]*365ers and Stockyards Act,7 all fail to grant authority to delegate the issuance of subpoenas. It appears that none of the agencies administering these acts has construed the authority of its head to include the power to delegate the signing and issuance of subpoenas.8 *10On the other hand, Congress, in numerous eases, has specifically authorized delegation of the subpoena power.9 In others it has granted the power to particularly designated subordinate officers or agents, thus negativing any implied power in the head to delegate generally to subordinates.10 The [366]*366suggestion that the Administrator is given authority to delegate the subpoena power because the applicable Trade Commission Act authorizes individual members of the Commission as well as the Commission itself to sign subpoenas overlooks the fact that the Administrator alone occupies a position under this Act corresponding to that of the Commissioners under their Act. The structure of the Trade Commission Act lends no support to the view that the Administrator has an implied power to delegate the signing and issuance of subpoenas to persons undesignated by the statute, a power not granted to or exercised by the Commission or its members.
All this is persuasive of a Congressional purpose that the subpoena power shall be delegable only when an authority to delegate is expressly granted. That purpose has been emphasized here not only by the authority expressly given to delegate the power to conduct investigations, and in the adoption by reference of the subpoena provisions of the Federal Trade Commission Act, which contain no authority to delegate, but by the legislative history of the present Act, which shows that the authority to delegate the subpoena power was eliminated by the Conference Committee from the bills which each House had adopted.* 11 Such authority expressly granted in the bill which passed the Senate, was rejected by the Conference Committee. It also discarded the provisions of the House bill which committed the administration of the Act to the Secretary of Labor, who has a general power of delegation under Rev. Stat. § 161, 5 U. S. C. § 22, and placed in his stead the Administrator, who was given only the subpoena powers of the Federal Trade Commission incorporated in the House bill.
[367]*367We cannot assume that Congress was of the opinion that the present agency, when appropriately organized for the purpose, would be any the less able to function without the power in the Administrator to delegate the signing and issuance of subpoenas than the Federal Trade Commission, the Interstate Commerce Commission, and other agencies which have not been given and do not assert the power. Nor can we assume, as the Government argues, that Congress is wholly without design in withholding the power in this case and granting it in others, or even if it had been, that it is any part of the judicial function to restore to the Act what Congress has taken out of it. Even though Congress has underestimated the burden which it has placed upon the Administrator, which is by no means clear, we think that the legislative record establishes that Congress has withheld from him authority to delegate the exercise of the subpoena power, and that this precludes our restoring it by construction.
