Reading a New Mexico ZIP code
New Mexico holds 427 ZIP codes between 87001 and 88439, spread over 33 counties. Albuquerque leads the state with 42 codes, ahead of Santa Fe with 11. Every code here opens with the digit 8: that opening number is the national postal region New Mexico belongs to, the next two digits name the sectional center that sorts the mail, and the final two point to the local office. A ZIP+4 suffix narrows delivery to a block face. Boundaries follow carrier routes rather than city limits, which is why Albuquerque spreads across 42 codes while some rural codes cross county lines.
