Medicine label glossary: what B. No., MFG, EXP, Reg. No., MRP, GTIN and other terms mean
Medicine packs and DRAP notices use a lot of short forms. The most important on the pack are B. No. (batch number), MFG (manufacturing date), EXP (expiry date), Reg. No. (DRAP registration number), MRP (maximum retail price) and, on new packs, GTIN, SN, BN and EXP beside the square 2D code. This glossary explains each one and what to do with it.

How the terms fit together on a real pack
Take a carton of antibiotic tablets. On the front you see the brand name and, smaller, the generic name and strength. On a side panel you find the Reg. No. and the maker's name with its DML. On the end flap, the B. No., MFG, EXP and MRP. If the carton was made from 9 October 2026, a small square 2D code sits beside four printed lines: GTIN, SN, BN and EXP. The strip inside repeats the batch and expiry.
Each term answers a different question. Is it approved? Reg. No. Is it still usable? EXP. Has it been recalled? B. No. Is this box genuine? SN, through a scan. Am I paying the right price? MRP, checked in our price search.
Terms that are often confused
| Confused pair | Difference |
|---|---|
| Reg. No. vs DML | Reg. No. identifies the product; DML identifies the factory. |
| Batch vs serial | Batch is shared by thousands of packs; serial belongs to one pack. |
| MFG vs EXP | Made on vs use until. |
| Spurious vs substandard | A fake vs a genuine product that failed a test. |
| Recall vs rapid alert | Withdrawal of named batches vs a warning about fakes or unregistered products. |
| Registration vs enlistment number | Drugs are registered; herbal and nutritional products are enlisted. |
| GTIN vs striped barcode number | Same product number; the GTIN in the 2D code is 14 digits, the retail barcode often 13. |
