Most people know their ZIP code from their front door. In Newark, though, a number of codes — 07101 and the 071xx series such as 07175, 07182, 07184, 07188, 07189, 07191 to 07195, 07198 and 07199 — are used mainly for post office boxes and for organisations that receive enough mail to have a code of their own. If your company letterhead or billing address uses one of these, this page is for you.
Why the street address matters
A PO box ZIP tells us where your mail is sorted, not where your door is. When you call, give us the street address of the building, the entrance we should use and a name for the person meeting us. Large sites often have a loading dock, a security desk or a separate visitor entrance; telling us up front saves time for everyone.
Work we do for organisations and offices
- Office and suite lockouts, including after-hours.
- Rekeying when staff leave or keys go missing.
- Master key systems so managers carry one key and staff carry only what they need.
- Mailroom, supply-room and cabinet locks opened, replaced or keyed alike.
- Keypad and electronic locks for rooms that change hands often.
- Panic bars and exit hardware repaired or adjusted.
Working with building security
Many organisations with their own ZIP code have a security team or a facilities manager who controls access. We are happy to work through them: we will confirm who authorised the job, sign in at the desk and leave a short note of what was changed. If your building requires a certificate of insurance or a vendor form before a contractor can come in, tell us when you book so the paperwork is ready.
Downtown offices
A lot of PO-box and organisational mail for Newark is handled through the downtown area, so many of the businesses using these codes sit near Broad Street and the courts and government buildings. For street-level details of that neighbourhood, see our Downtown Newark (07102) page.
Nearby areas we also cover
