Aadhaar ↔ bank pairing without jamming NPCI retries

Seeding etiquette, name harmonisation across UIDAI-Bank-Core, and what to escalate when hyphenation mismatches linger.

NPCI’s mapper honours exact byte strings. A middle initial missing in CBS but present in UIDAI often blocks ₹1 test credits even when humans swear it is “the same farmer.”

Field checklist

  • Request bank branch ASCII printouts showing full name parity with UIDAI portals.
  • If you migrated accounts after merger, insist on mapper refresh—not only passbook printing.
  • For joint accounts, map the operative single signature account used for fertilizer subsidies.
Never pay for “instant Aadhaar linking”; banks perform mapper updates without brokerage.
