This code is the low end of the range of +4 Codes that pertain to this ZIP Code. ZIP+4 Codes associated with nondelivery areas are composed of valid ZIP sector numbers and "ND" for the ZIP segment number, for example 12345-12ND. Non-deliverable areas are areas to which the USPS does not deliver mail, such as vacant lots and land that borders railroad tracks. Mailers should not match an address identified as a nondelivery area. If you absolutely must have numeric characters in the Plus4Code column, you may treat "ND" values as "00" (zero zero).
