Brazil’s Company Tax ID Gets Letters From July 1
Brazil's company tax ID, known as CNPJ, will start including letters from July 1, in addition to numbers. The new alphanumeric format will have 14 characters, with the first eight and next four being alphanumeric and the last two remaining numeric. This change is intended to increase the number of possible combinations, as the previous numbers-only system was nearing its limit.
- ▪From July 1, Brazil starts issuing company tax IDs that mix letters and numbers, not digits alone.
- ▪Every current CNPJ stays valid, with no re-registration and no fee, and the change applies only to new registrations.
- ▪More than 63 million CNPJs have been issued and the numbers-only system was nearing its limit of combinations.
