North Andover Postal Coverage
Only one standard postal ZIP was located for the North Andover postal city: 01845. The official town site uses that code, and the USPS label list maps it to North Andover. It is a standard street-delivery ZIP for town residential, civic, and business addresses as USPS assigns them. That ZIP code is a delivery designation, not an official postal polygon. It also does not establish that every mailing address associated with the post office lies in the town for tax or parcel purposes.
| Postal ZIP | Postal city found | Post office | Verification note |
|---|---|---|---|
| 01845 | North Andover | North Andover Post Office, 131 Main Street | Standard delivery; check the complete address with USPS |
The USPS North Andover Post Office listing identifies the local facility at 131 Main Street, North Andover, MA 01845-9998.
The facility listing supports a postal-address check, while a parcel or municipal question still belongs with the town’s property and mapping records.
Confirming a North Andover Address
USPS ZIP Lookup offers three distinct checks. By Address accepts a street address with city and state, or an address with a ZIP. By City and State returns the ZIPs associated with that city. Cities by ZIP starts with the postal code and returns associated city labels. For a specific address, the address mode is the most direct authority because it tests the whole delivery address rather than assuming a town name guarantees the result.
| USPS mode | Information entered | Useful result |
|---|---|---|
| By Address | Street address with city/state or ZIP | Delivery ZIP and preferred postal city |
| By City and State | City and state | ZIPs associated with the entered city |
| Cities by ZIP | Postal ZIP | City labels USPS associates with that code |
A correct result verifies postal formatting. A ZIP code result does not identify a resident, establish the municipal boundary, or replace a deed’s legal description. The city-and-state mode can be useful when checking whether a town label has more than one postal association, but it is not a substitute for entering the full address. The Cities by ZIP mode is useful for checking a label, not for proving that the whole listed city falls inside the delivery area.
North Andover ZIP Directory Limits
Myth: a postal code is not a town-wide resident roster. The Secretary of the Commonwealth voter form requires a five-digit residential ZIP, but it also requires first name, last name, date of birth, and an individual-use acknowledgment. It is meant for a voter to check their own status. It has no ZIP browse or street list, and it cannot be used to enumerate everyone in 01845.
M.G.L. c. 51 §37 treats the annual register differently from the online form. It places eligible voters and a residence field in the register, while protected voters can be suppressed. The register still does not describe every person at an address, and its public status does not turn the personal form into a bulk lookup. The Town Clerk can explain local inspection procedure, current status, and protected-record limits without promising an online ZIP list.
Likewise, a property record may show an owner’s mailing ZIP that is outside North Andover. That field can be a contact clue, but it is not evidence that the owner occupies the parcel. A ZIP code in a mailing field is especially weak as proof of a current person-to-parcel connection. The town’s assessor, MapGeo, registry, and permit records are keyed to other fields for good reason. The North Andover ZIP code directory should narrow a postal question, then hand a legal or parcel question to the right custodian.
North Andover Parcel and Mailing Fields
A municipal address record has several layers. The situs is the physical parcel or building address. The mailing field belongs to the owner correspondence record and can be elsewhere. A deed’s legal description and the assessor parcel or map-lot identifier are the stronger bridge when a number changed, a lot was subdivided, or an older source used a different town name. Keep every layer in the research notes instead of collapsing them into one address.
| Address element | Primary keeper | What it identifies |
|---|---|---|
| Situs address | Assessor, GIS, permit, registry street search | Physical parcel or building |
| Owner mailing field | Assessor and tax roll | Owner correspondence, not occupancy |
| Legal description | Deed, plan, Land Court record | Parcel identity across numbering or subdivision changes |
| Parcel or map-lot | Assessor, GIS, registry | Cross-record land reference |
| Postal city and ZIP | USPS | Delivery formatting, not jurisdiction |
Historical directories add another layer. Their address entries are snapshots of a past occupant or business location, and many North Andover sources use Andover or North Parish in older periods. They do not use a modern postal code as a stable historical key. A deed book and plan, a directory title, and a dated map are better tools for bridging old and current address descriptions.
Finding Records by North Andover ZIP
A ZIP-oriented search should end with a clearly labeled record set, not a claim that it lists every person. The safe order is to verify the postal format first, then see whether a current town tool actually exposes a filter for the needed field. If a portal returns parcels, describe the result as parcels. If it returns an owner mailing field, describe that role accurately. The process is useful for civic and property research because it keeps delivery data from being mistaken for residency data.
- Use USPS address or city-and-state mode to confirm the postal city and delivery ZIP.
- Search the property address in the assessor or MapGeo system and note the situs and parcel identifier.
- Use a town boundary, parcel, or legal-description check before attributing a postal address to North Andover municipal records.
- Report selected property records as records, not as a full population or resident enumeration.
- When the question narrows to a street, use the North Andover street directory for the address-keyed record trail.
North Andover Records Tool Limits
The Patriot Properties WebPro card displays owner mailing city, state, and ZIP and may be searched by owner, address, or map information. The accessible static instructions did not prove that it has a ZIP filter. North Andover MapGeo supports quick searching by address, owner, or property ID, but a North Andover advanced ZIP field was not confirmed. Do not describe either tool as a ZIP-wide parcel search unless the live interface visibly offers that field.
The Registry’s searches are keyed to municipal town and street, not ZIP. OpenGov permit search may take an address, but no ZIP-wide mode was located. The voter-status form uses a ZIP only as one part of an individual match. No confirmed North Andover ZIP code filter was found in these town tools. These limits are practical: the town uses parcel and street systems, while USPS controls delivery verification. When a form does not show the needed field, a written question to the town office or a request under the Public Records Law is a more accurate next step than inferring a hidden search option.
North Andover Delivery Boundaries
Postal boundaries and town lines are different layers. North Andover touches Andover, North Reading, Boxford, Middleton, Methuen, Haverhill, and Lawrence, so a postal relationship near a town edge must be checked against the parcel situs and municipal map. No official current ZIP polygon and no documented ZIP split or realignment year were located in the research. It would be inaccurate to assign particular edge streets to one side of a delivery boundary without a current USPS address result.
Boundary check. Use USPS for the complete delivery address and town GIS or assessor records for the municipal parcel; neither result substitutes for the other.
North Andover Postal Definitions
Postal shorthand can make records look more precise than they are. These terms help separate a delivery label from a land-record identifier.
- ZIP
- A USPS delivery-routing code. It identifies postal service, not a legal municipal boundary.
- ZIP+4
- An added four-digit routing segment that can narrow a delivery sequence beyond the basic five-digit ZIP.
- P.O. box ZIP
- A ZIP associated with post-office boxes, which may not describe a street-delivery area.
- Unique ZIP
- A ZIP assigned for a single large addressee or organization. No such North Andover ZIP was located in the research.
- Carrier route
- A mail-delivery route within postal operations. It is not a resident directory or municipal district.
North Andover Geography and Town Counts
North Andover separated from Andover on April 7, 1855. That older boundary matters when a directory, deed, or North Parish record uses Andover rather than the modern town name. Postal geography is newer and serves a different purpose, so an old address cannot be translated simply by attaching a modern ZIP. Use the historic town name, deed plan, directory title, and nearby institutions to bridge the record to a present parcel. The former North Parish, Old Center, and mill-village references can supply context, but the legal description and source date remain the key checks.
Census QuickFacts reports 30,915 people in North Andover in 2020 and a 2025 estimate of 32,161. Those are town figures, not figures for 01845. ZIP codes are delivery constructs, while Census ZIP approximations are statistical tools. The difference is why a ZIP code directory should never present a postal code as a municipal population count. The North Andover ZIP code directory is a postal reference, not a town census.
