Overview
Understanding ZIP code 01840
ZIP code 01840 is assigned to Lawrence, MA, and falls within Essex County. Like every US postal code, it began as a mail-routing device rather than a geographic boundary — the US Postal Service groups delivery routes under a single code so carriers and sorting equipment can process mail efficiently. Today it also serves as a practical shorthand for the area itself: roughly 7,092 people live inside it.
At 13,906 residents per square mile spread over 0.51 square miles, 01840 reads as a dense urban area. It is a smaller postal code by population, and density shapes almost everything else on this page — how people get to work, whether they own or rent, and what housing costs.
Household earnings are well below the national median. At $34,630, 01840 ranks among the lower-income postal codes, ahead of 3% of them. The US median for comparison is $70,109. Bear in mind that median income describes the midpoint household, not the average — it is not pulled upward by a handful of very high earners the way a mean would be.

Where to stay in Lawrence, MA
Lawrence sits in a densely built environment, and accommodation in and around 01840 tends to reflect that — full-service hotels, boutique properties and serviced apartments packed close together, usually within walking distance of transit.

Practical uses
What ZIP code 01840 is used for
Beyond addressing mail, 01840 does a lot of quiet administrative work. Retailers use it to calculate shipping and sales tax at checkout. Insurers use it to set premiums, since risk profiles vary geographically. Employers and marketers use it to define service areas. Government agencies use it to route benefits and organise reporting. If you have ever been asked for a postal code by a form that clearly does not intend to send you anything, this is why.
For anyone weighing a move, 01840 offers a compact profile of Lawrence: 7,092 residents, a median household income of $34,630, 13.5% of adults holding a bachelor's degree or higher, and an unemployment rate of 7.8%. A handful of figures like these answer more relocation questions than most neighbourhood guides do.
One caution worth repeating: a postal code is not a neighbourhood. 01840 may cover parts of several distinct areas, and a single neighbourhood in Lawrence may be split across more than one code. Boundaries also shift as USPS adjusts delivery routes. Treat the figures here as describing a delivery area, which is what they actually measure.
