Mail has been automated for decades behind the scenes: machines read addresses and sort letters into the order a carrier walks the route. Email and online bills cut volume, while parcels keep growing. Someone still carries it all to the door.
The short answer: AI and automation are squeezing sorting work more than delivery. The ILO's 2025 index puts mail carriers and sorting clerks in gradient 2, at 0.41, mostly because of the clerical and sorting tasks in that group. The US Bureau of Labor Statistics projects no change for mail carriers and a 1 percent decline for postal service workers overall from 2025 to 2035, with about 32,200 openings a year. Projections are estimates, not guarantees.
How exposed mail carriers are
The International Labour Organization scores occupations' tasks from 0 (cannot be automated with generative AI) to 1 (could be done without a human operator), and groups them into gradients from 1 to 4, with 4 the most exposed; below them sit minimal exposure and not exposed (ILO Working Paper 140, 2025).
| Occupation (ISCO-08) | ILO category | Mean task score (0 to 1) |
|---|---|---|
| Mail Carriers and Sorting Clerks | Gradient 2 | 0.41 |
The ILO groups carriers with sorting clerks. Walking or driving a route is far less exposed than sorting and counter work.
What the BLS projects
| Occupation | Projected change 2025 to 2035 | Openings a year |
|---|---|---|
| Mail carriers | No change (0%) | Part of 32,200 for all postal service workers |
| Postal service workers (all) | Decline 1% | About 32,200 |
The BLS says new sorting technology can read text and automatically sort, forward and process mail, that digital communication reduces mail volume, and that more centralized delivery, such as cluster mailboxes, cuts door-to-door deliveries.
What technology is taking on
- Reading addresses and sorting mail into delivery order.
- Planning and adjusting delivery routes.
- Package tracking and delivery notifications.
- Answering routine questions about services online.
What stays with the mail carrier
- Delivery: traveling routes in cities, towns and rural areas, delivering and collecting mail.
- Customers: answering questions about postal services and selling stamps and money orders.
- The route: knowing addresses, hazards and the people on it, and noticing when something is wrong.
- Checking: route plans and automated answers can be wrong, which NIST calls confabulation (NIST AI 600-1). See checking AI output.
How the job is changing
More of the day goes to parcels and less to letters, and sorting happens before the carrier starts. The job stays physical and local.

Pay and how to get in
The US Bureau of Labor Statistics puts the median annual pay for postal service workers at $59,880 in May 2025, against $50,980 for all workers. The typical education needed to enter is: no formal educational credential. See how this job compares in AI exposure by pay and AI exposure by education level.
Questions and answers
Will AI replace mail carriers?
Not on current evidence. The BLS projects no change for mail carriers from 2025 to 2035. Sorting is the part most affected by automation.
How exposed are mail carriers to generative AI?
The ILO puts mail carriers and sorting clerks in gradient 2, with a mean task score of 0.41, largely from sorting and clerical tasks.
Why is postal employment flat?
The BLS cites automated sorting, lower mail volume from digital communication and more centralized delivery such as cluster mailboxes.
What postal work stays human?
Delivering and collecting on routes, serving customers and knowing the route, plus checking automated plans.
