How to Verify a GCA Invitation Letter

To verify a Global Conference Alliance invitation letter, open the official verification portal, enter the Registration Number and Passport Number printed on the letter, and confirm the details match an active paid registration. Do not use a letter that fails verification for a visa application.

Use only official GCA verification tools before trusting a letter or submitting it with a visa application.

Open verification portalUse on-site verification form

  1. Step 1

    Find the identifiers on the letter

    Locate the Registration Number and Passport Number printed on the invitation letter. Both must match the details used at registration.

  2. Step 2

    Open the official verification portal

    Use only GCA-owned tools: the external portal or the on-site form. Do not enter details into third-party “verification” sites that claim to check GCA letters.

  3. Step 3

    Submit and read the result

    A successful match confirms the letter is linked to a genuine paid registration (name, conference, and status). “Not found” means do not trust the letter for a visa.

  4. Step 4

    Still unsure?

    Contact GCA at [email protected] with a scan of the letter, or review the fake-letter guide before paying any extra fees.
