South Yemen Reference Page | Serial Number Prefixes
There were two series of notes issued in South Yemen and each series carried a different format of serial number prefix .
The prefix of the notes issued by the SACA consisted of a Latin letter followed by a western number. All denominations carried the same style of prefix. The serial number prefix started at A1 and incremented in the following manner:
| A1, B1, C1, etcetera to Z1 | then ... |
| A2, B2, C2, etcetera to Z2 | then ... |
| A3, B3, C3, etcetera to Z3 | and so on ... |
The letters 'I' and 'O' were not used in the sequence as they resembe the numerals 1 and 0.
The notes issued by the Bank of Yemen carried serial number prefixes in the format of 'Series and denomination letters'. The fractional prefix contained two Arabic letters over a number built with western numerals. The left-hand Arabic letter was the 'Series' letter and the right-hand letter was the 'Denominational' letter. As there was only one series produced, all notes carry the letter ا (alif). The letters assigned to each denomination are in the chart below (used in the numeric sequence of the alphabet). The number below the Arabic letters started at 1 and incremented as the series continued. The prefixes of the 500-fils notes would increment in the following manner: با/1, با/2, با/3, با/4, et cetera. For replacement notes, the number was replaced by the Arabic letter س (so a replacement note for the 500 fils would have the prefix of: س/با).
| Denomination | Letter |
| 500 Fils | ب |
| 1 Dinar | ج |
| 5 Dinars | د |
| 10 Dinars | هـ |
