Why Verify Signatures on Official Registry Extracts?
Official registry extracts carry legal weight only when validated with a qualified digital signature. Banks, notaries, and courts require signature verification protocols.
File Structure of Official Extracts
Depending on the agency, documents arrive in specific formats:
- EGRUL Tax Extract (FNS): A PDF document accompanied by a detached .sig signature file issued by the tax authority.
- Real Estate Extract (EGRN): A ZIP package containing an XML payload and an accompanying .xml.sig (or .p7s) signature file.
Step-by-Step Verification Guide
- Open our free verification tool FormatShift /verify-sig.
- Drag and drop your signature file (.sig or .p7s). The certificate details will load instantly.
- Optionally attach the companion PDF or XML extract to verify hash integrity.
- Review the verified protocol: signer identity, tax IDs, and authority validity.
Frequently Asked Questions
Is CryptoPro required to check registry extracts?
No. Certificate inspection, validity dates, and signer information are parsed directly in your browser without mandatory software installations.
What if I received only a .SIG file without a PDF?
If the signature is attached, the document is embedded inside the container. Upload it to our verifier to extract and download the original PDF with one click.
