# Translations: RS Address Format/19/en

From ArdorDocs

Reed-Solomon (RS) addresses for Ardor are encoded as follows:

- Take the original 64-bit account ID, add 1 zero bit to get 65 and then split it into thirteen 5-bit "symbols" (65 / 5 = 13).
- Order the symbols from lowest bit to highest bits, in little-endian order, i.e. bits 0-4, 5-9, 10-14, etc. up to 60-64.
- Append 4 symbols of parity (20 bits), produced by the Reed-Solomon encoding of our 13 symbols from step one (which are left untouched). This produces a 13 + 4 = 17 symbol codeword.
- Scramble the codeword symbols in a predefined order and encode them 1-to-1 with an alphabet of 32 characters, splitting them into groups by dashes.
