+- Accept Nigeria's (NG) 11-character digital postcode, such as `EK-01-A03-FK-01`, alongside the six-digit code. NIPOST launched it in October 2026. Thanks to ~ @Adeniyikayodee
 - Fix the Moldova (MD) postcode pattern: accept the canonical `MD-####` form and bare 4-digit codes, and reject non-`MD` letter prefixes. The previous pattern required any two letters and rejected the hyphenated form — fixes #73
