guidelines for use of registration numbers

The Register of Professional Archaeologists (the Register) assigns a permanent registration number upon registration. The Register encourages registrants to use this number in their professional practice to highlight their registration, certify their work products, and differentiate themselves from non-registered archaeologists. Identifying yourself as a Registered Professional Archaeologist (RPA) in good standing, in any form, when you are not a RPA (i.e., are not formally registered, or your registration has expired due to not paying your annual registration fee) is a violation subject to legal action.


Registration numbers can be found in your online profile.

You may use your registration number anywhere you use your name in professional writing, correspondence, or promotion (e.g. business cards, web sites).

The preferred format is: Registered Professional Archaeologist 10331

The alternative, abbreviated format is: RPA 10331

Note that no punctuation or number signs are used in either version of the format. Capitalize the first letter of the words Registered Professional Archaeologist in the preferred format. Capitalization also is used in the plural, for a group of Registered Professional Archaeologists. In this latter, group, case registration numbers are not used.

Use of “RPA” or “Registered Professional Archaeologist”, without a number, in either the preferred or abbreviated formats is discouraged when referring to an individual Registered Professional Archaeologist.

The heading “Registrations” should be used, with your registration information listed under the heading.
