The 24 Standard codes are the ones that cover an actual residential or commercial area: places like Algiers, Bywater, Carrollton, and Gentilly each sit inside their own Standard ZIP. The 26 PO Box codes carry no residents by definition. The 11 Unique codes are where the count runs past what a neighborhood map alone would suggest, and three of them are covered in detail further down this page: a university, a military base, and a public utility, each with its own dedicated code.

The table lists all 61 currently assigned codes, cross-checked across independent ZIP directories (Zipcodes-US.com, WorldPostalCode.com). Numbers missing from the sequence, like 70120 or 70132 through 70138, were never assigned or have since been retired: USPS builds a range as delivery areas are created, it doesn’t fill one end to end. For a specific address, the USPS ZIP Code Lookup tool is the canonical source and will catch any recent additions or retirements this table doesn’t.
Which ZIP Code Is Your Neighborhood?
| Neighborhood | ZIP Code(s) |
|---|---|
| Algiers | 70114 |
| Bywater | 70117 |
| Carrollton | 70118 |
| Gentilly | 70122 |
| French Quarter | 70112, 70116, 70130 |
| Elmwood / Harahan / River Ridge | 70123 (Jefferson Parish) |
| English Turn / Algiers South | 70131 |
Most named neighborhoods fall inside a single ZIP code. A few straddle two or three, and the French Quarter is the sharpest example on this list.
The French Quarter’s Three ZIP Codes
The French Quarter carries three separate ZIP codes at once: 70112, 70116, and 70130. The split runs roughly along Rampart Street, Canal Street, and the blocks nearest Jackson Square, according to neighborhood mapping from Statistical Atlas and Homes.com’s local guide. Two addresses on the same block of Royal Street can carry different ZIP codes, depending on which side of an internal line they fall.
What ZIP code is the French Quarter?
Three: 70112, 70116, and 70130, divided by internal boundaries rather than covered by one code.
Why 61 Codes Cover Only About Twenty Neighborhoods
Standard codes map to neighborhoods. PO Box codes hold no residents at all, by definition. The 11 Unique codes are where the gap between “61 ZIP codes” and “about twenty real places” opens up: each Unique code is carved out for one institution’s mail volume, not a residential area.
The Institutions Behind the Unique Codes
| ZIP Code | Institution | Status |
|---|---|---|
| 70148 | University of New Orleans (LSU New Orleans), 2000 Lakeshore Drive | Active |
| 70143 | Naval Air Station Joint Reserve Base New Orleans, Belle Chasse | Active |
| 70165 | Sewerage & Water Board of New Orleans, 625 St. Joseph Street | Active |
The pattern holds beyond these three: eight more Unique codes on the full list belong to institutions of the same kind, confirmed through their own contact pages rather than a third-party directory. UNO’s own contact page lists 2000 Lakeshore Drive under 70148. The Sewerage & Water Board’s contact page lists departments from Finance to the 24-hour emergency leak desk all under 625 St. Joseph Street, 70165, an agency the Louisiana Legislature authorized in 1899 to run the city’s water, sewer, and drainage systems. NAS JRB New Orleans’s own base directory lists 70143 for facilities on Russell Avenue in Belle Chasse.
Why do some New Orleans ZIP codes have no residents at all?
Because they’re Unique codes assigned to one institution’s mail volume, not a neighborhood, covering entities like a university, a military base, and a public utility.
Where ZIP Codes Stop Matching the Parish Line
New Orleans and Orleans Parish are the same place, with the same boundary and the same population count, according to The Data Center’s analysis of Census figures. The 701 ZIP prefix isn’t limited to that boundary, though. ZIP 70123, covering Elmwood, Harahan, and River Ridge with roughly 27,300 residents, sits entirely inside neighboring Jefferson Parish. The Jefferson Parish Sheriff’s Office says so directly, in its own tax-guidance FAQ: the Postal Service assigns the 701 prefix as “New Orleans” even though 70123 sits completely outside Orleans Parish.
Is a New Orleans ZIP code the same as being in Orleans Parish?
No. ZIP 70123 carries the “New Orleans” postal name but sits entirely in Jefferson Parish.
Population, Then and Now
The 2010 Census counted 343,829 residents in New Orleans, a drop of 29 percent from 2000, according to a Census Bureau release issued that year. By the 2020 Census that had recovered to 383,997, per Census Bureau QuickFacts.
Finding the Exact ZIP for One Address
The USPS ZIP Code Lookup tool resolves a single address to its exact ZIP+4, which is most useful exactly where this page shows overlap: French Quarter block edges, and the Jefferson Parish sliver inside 70123.
