What do you do when a seal number on your document is too blurry to read?
TL;DRA Russian vocational diploma and its four-page supplement carried the issuing institute’s round seal. The seal’s 13-digit registration number, the OGRN, was printed in fine curved type, and two digits were blurry enough to misread. We produced two candidate readings and tested both against the OGRN check-digit algorithm. Only one reading passed, so that number went into the certified translation, with a Translator’s Note on record. The translation was delivered for the client’s USCIS filing.

What We Received
A client ordered a Russian diploma translation for USCIS — a vocational diploma (диплом о среднем профессиональном образовании) plus its four-page supplement. Both impressions of the issuing institute’s round seal shared one problem: a blurry seal number in fine curved type.
The diploma was issued in 2024 by a private institute in Chelyabinsk, Russia. It certifies a vocational qualification in computer programming.
The translation was needed for a USCIS immigration filing. The seal’s outer rings name the education ministry and the institute. An inner band prints the institute’s 13-digit state registration number, called the OGRN.

Why This Required Special Handling
USCIS expects a complete and accurate translation of the whole page. Seals and stamps are content, not decoration — their text gets translated too.
On this seal, the digit band curves tightly, and the ink thins where the curve bends. One blurry digit could be a 3 or an 8. Another could be a 0 or a 3.
A translator cannot pick between readings by eye and hope. A wrong digit in a state identifier is an accuracy error. Marking the whole number illegible would discard information that was actually recoverable.
How We Handled It
We cropped the seal at high resolution and rotated the curved band until it read horizontally. That produced two candidate readings, different in exactly two digits.
The OGRN has a built-in defense against this exact problem. Its thirteenth digit is a check digit: divide the first twelve digits by 11, and the last digit of the remainder must match it.
One candidate reading failed that test. The other passed. The same seal is stamped on both the diploma and the supplement’s final page, and the passing reading matched both impressions.
"Translator’s Note: The registration number (OGRN) in the round seal is printed in fine curved type. The number has been transcribed and verified against the OGRN check-digit algorithm; ring text too small to resolve is marked as partially illegible."
The rest of the seal was translated in full — the ministry ring, the institute’s name, and its abbreviation. Micro-text that stayed unreadable was marked partially illegible, never guessed.
The Outcome
The certified translation was delivered for the client’s USCIS filing. Every seal impression was translated in full.
The registration number in the translation is arithmetic-verified, not guessed. It reads the same in both places the seal appears, so the document stays internally consistent.
What This Means for You
A blurry seal number is not automatically an illegible one. Many official identifiers carry a built-in check digit — the Russian OGRN is one of them — so a doubtful reading can be tested instead of guessed. Ask for a certified translation that covers every seal and stamp, and marks anything unverifiable as partially illegible.
