An Oklahoma land surveyor seal must carry Licensed Professional Surveyor, Oklahoma, your license number and your name as it reads on your Certificate of Licensure, with two concentric circles, in the 1-7/8 inch or the 1-5/8 inch size. Your signature and its date go beside or across the seal. The seal image must carry through to copies. This page covers wording, sizes, devices, signing, documents and lapse.

What must appear on an Oklahoma land surveyor seal?
Five elements, all set by Okla. Admin. Code 245:15-17-1(c). They are the legend Licensed Professional Surveyor, the word Oklahoma, your license number, your name as your Certificate of Licensure gives it, and a pair of concentric circles.
Match the name to the certificate letter for letter, including any middle initial it shows, rather than using a shortened form. For layout ideas within those elements, see our Oklahoma land surveyor stamp design tips.
Which seal sizes does Oklahoma allow?
Two: a 1-7/8 inch seal and a 1-5/8 inch seal. Both are named in Okla. Admin. Code 245:15-17-1(c) and Appendix A to ch. 15, so either one complies and the choice is yours. Pick the size that sits best in your title block.
The rule states these two sizes rather than a range, so order one of them exactly. Our article on Oklahoma land surveyor stamp and seal specifications goes further into the specifications.
Which devices can produce a compliant Oklahoma seal?
Electronic digitization or a rubber stamp, provided the seal image is accurate and legible. Okla. Admin. Code 245:15-17-1(b), 245:15-17-2(b) allow both routes, and the safer purchase of the two is a rubber stamp.
If you are considering an embosser, weigh it against the image requirement in the next section before relying on it. Our piece on Oklahoma land surveyor seal embossers describes that tool.
Why must an Oklahoma seal show up on copies?
Because the rule calls for a seal type that leaves an image on original documents and on duplicates made from them. Okla. Admin. Code 245:15-17-1(b), 245:15-17-2(b) set that reproduction test, so an impression that vanishes on a copy fails it.
Test a new device by photocopying or scanning a stamped sheet before the first real job. If the copy loses the seal, the device is not doing what the rule asks.
Where do the signature and date go?
Beside the seal or across it, every time the seal is applied. 59 Okla. Stat. § 475.15(C) requires your signature and the date you signed at that spot, and a wet-ink original is not required.
Either position complies, so settle on one layout for your title block and use it consistently across a project. Consistency makes a missing signature or date easy to spot at review.
Which Oklahoma documents need the seal?
Every final surveying document delivered to a client or a public agency. Under Okla. Admin. Code 245:15-17-2(a), (c), (i) that covers plats and surveys, plans and drawings, specifications and reports, and design information and calculations.
The word final carries the weight, and the list is wide enough to take in calculations as well as drawings. Our summary of Oklahoma stamp and seal guidelines for surveyors is a related read.
Can you seal electronically in Oklahoma?
Yes. Electronic sealing is permitted, and Okla. Admin. Code 245:15-17-2(g) does not specify a certificate authority or any particular technology. The device rule already counts electronic digitization as a permissible way to produce the seal image.
The software choice is therefore yours, provided the image of the seal stays accurate and legible. Run the same copy test on an electronic seal that you would run on a stamped one.
What happens at renewal, expiration or revocation?
Renewal leaves a compliant seal in service; expiration or revocation takes it out. Under 59 Okla. Stat. § 475.15(A), (C), (D) your license number is your own serial number and survives renewal, while affixing the seal after an expiration or a revocation is unlawful.
There is no reason to reorder at each renewal. What matters is keeping the license current so the seal stays usable.
What should you send when ordering an Oklahoma seal?
Your name exactly as your Certificate of Licensure shows it, your license number, and your choice of the 1-7/8 or 1-5/8 inch size. Oklahoma, Licensed Professional Surveyor and the two concentric circles are fixed by the rule.
Keep the certificate at hand while you fill in the order, and copy from it rather than from memory. The name and number on the seal have to agree with it.
How do you check an Oklahoma impression before first use?
Measure it, read it and copy it. Confirm the overall size matches the 1-7/8 or 1-5/8 inch option you ordered, check the name against your certificate and the number against your license, and run a photocopy to test the reproduction requirement.
Keep one approved test impression on file for comparison with later orders. Our checklist of features to check on an Oklahoma land surveyor seal is a handy companion.
Frequently asked questions
Is one of the two sizes preferred?
No. Okla. Admin. Code 245:15-17-1(c) and Appendix A to ch. 15 name both, and either complies. Choose the one that fits your title block and keeps the lettering easy to read.
Does the seal need an expiration date?
No expiration date appears among the elements in Okla. Admin. Code 245:15-17-1(c): your name, license number, Oklahoma, Licensed Professional Surveyor and the two circles. Renewal alone changes none of those elements.
Does the accurate and legible test apply to electronic seals too?
Yes. The same provision that permits electronic digitization requires the result to be an accurate, legible seal image, just as it does for a rubber stamp.
Can someone in my office apply my seal after my license expires?
No. Under 59 Okla. Stat. § 475.15(C), it is unlawful for you to put your seal on a document, or to let it be put there, after expiration or revocation. A colleague applying it falls within that bar.
Is an embosser one of the named devices?
The devices the rule names as permissible are a rubber stamp and electronic digitization. An embosser is not among them in the sources behind this page, so measure one against the image requirement before relying on it.
