Online Ordering

Shopping online at NTIS is safe and secure. NTIS accepts payment online either by major credit card or an NTIS Deposit Account.

It encrypts all of your personal information, including credit card or deposit account number, name, and address, so that it cannot be read as the information travels over the Internet.

RUSH Service (Telephone orders only)

Call 1-800-553- 6847 or (703) 605-6000

NTIS offers its customers a RUSH Service option for an additional fee. RUSH orders can be placed over the phone for in-stock paper documents, for documents that have already been digitized and that are being ordered in CD-ROM format, and for in-stock audiovisual products. These orders are processed by NTIS within one business day, and then shipped the following business day by overnight courier to addresses within the U.S. or by airmail to addresses outside of the U.S. Because RUSH Orders are prioritized and in many cases filled within minutes, they cannot be modified or cancelled. (Computer products also may be ordered on a RUSH basis, but please allow 1-3 business days for inhouse manufacturing of computer products.) Simply call the telephone number above, and an NTIS Sales Representative will advise you if the product you are seeking is available for our RUSH Service.
