Bad addresses are expensive
- 1
Failed deliveries and returns
Packages bounce, shipments delay, customers churn. The average failed delivery costs $15–20.
- 2
Customer frustration
People give up when forms reject their address. Bad data at the start creates problems everywhere downstream.
- 3
Duplicate records and wasted money
Messy addresses create duplicate customer records, throw off reports, and waste money on mailings that never arrive.

Why people choose Addrex
Most address tools just say "pass" or "fail." We think you deserve to know what happened and why.
You See What Changed
Every address shows exactly what was fixed — a misspelled city, a missing ZIP code, a corrected street name. No mystery, no guessing.
Same Results Every Way
Whether you upload a spreadsheet, type one address, or connect an app — the same engine checks and fixes your data. Consistent every time.
No False Promises
We don't pretend to be USPS. We check addresses against our own database of 259M+ U.S. records and tell you exactly how confident we are.

Three steps. No coding required. No software to install.
Upload or type
Paste a single address, upload a spreadsheet, or connect via API — whatever works for you.
We check & fix
Addrex compares your addresses against 259M+ U.S. records, corrects typos, fills in missing details, and adds map coordinates.

Everything you need to get addresses right
Fix typos, verify against real data, add map coordinates, and download clean results — with or without code.
Extract addresses from messy text
NewPaste a block of text and Addrex finds the addresses buried inside, cleans them up, and verifies each one. Perfect for cleaning up notes, emails, claim documents, or any text with addresses in it.
