ESME_RINVSRCADR in SMPP

What is ESME_RINVSRCADR?

ESME_RINVSRCADR (Error Code: 0x0000000A) is an SMPP error indicating that the source address (sender ID) provided in the request is invalid or not permitted by the SMSC.

Possible Causes

  • The source_addr field is empty or incorrectly formatted.
  • The sender ID is longer than the maximum allowed length (typically 11 characters for alphanumeric sender IDs).
  • The sender ID contains unsupported characters.
  • The sender ID is not registered or whitelisted on the SMSC.
  • The sender ID type (source_addr_ton and source_addr_npi) is incorrect or not supported.

When Does It Happen?

This error occurs when submitting an SMPP PDU (such as submit_sm) with an invalid or unsupported sender ID.

Issue: The source_addr is empty, causing the SMSC to reject the request.

How to Solve It?

  • Ensure that the source_addr (sender ID) is correctly formatted and within the allowed length.
  • Use a valid source_addr_ton and source_addr_npi:
    • For alphanumeric sender ID: source_addr_ton = 5, source_addr_npi = 0
    • For numeric sender ID: source_addr_ton = 1, source_addr_npi = 1
  • Verify with the SMSC provider whether the sender ID needs to be pre-approved.
  • Check for any character restrictions enforced by the SMSC.
  • Enable debugging logs to inspect the exact value being sent in the PDU.

If the issue persists, contact the SMSC provider to confirm sender ID requirements.
