## In short

Located at 1311 Cambridge Street, the United States Postal Service branch in Cambridge, Massachusetts, has garnered a reputation that reflects a mix of experiences. With a modest rating of 3 stars from 41 reviews, customers often express frustration over the service, particularly citing the demeanor of certain staff members. Many have reported encounters with an employee known for his brusque manner, which has led to a perception of unwelcoming service. While some patrons have noted occasional courteous interactions, the overall sentiment suggests that this location may not be the most pleasant choice for postal needs.

Every fact on this page carries one of three marks: Confirmed (from their website, Google Business Profile, review sites, licensing boards, or measured by Local AI Registry), Visitor submitted (added by a person, with a date and how they know), or AI guess (what AI engines like Gemini and ChatGPT are saying, not confirmed by anyone). Every mark points to a reference at the end of this page.

## What AI gets wrong about United States Postal

We ask Gemini and ChatGPT about United States Postal. These are the answers that disagree with the record.

ChatGPT and Gemini, read by Local AI Registry on Oct 12, 2026.

No capture has disagreed with the record yet.


## The AI Score: 55 of 100

The AI Score measures how likely AI engines are to recommend a business, and how accurately. Cambridge post offices run 46 to 62. Fair starts at 45, good at 65. United States Postal scores 55, below the Cambridge average of 56. The same method scores every business on the registry.

| Signal | Weight | Score | What it measures | United States Postal |
| --- | --- | --- | --- | --- |
| Retrieval grounding | 26 | 100 | Whether you appear in the ranked results AI retrieves and cites: AI-Overview citations, organic top-10 for your money queries, and the Bing index ChatGPT leans on. | Good |
| Off-property attestation | 20 | 39 | Volume and consistency of what others say about you: YouTube mentions, branded web mentions, third-party “best-of” lists. The cause of retrievability. | Poor |
| AI visibility | 14 | 24 | Whether ChatGPT, Gemini, Perplexity, and AI Overviews name you, and whether they name you for the right service. | Named in 4 of 17 answers that recommended anyone. 5 more named nobody, which is not a loss and is not scored. |
| Reviews & response | 12 | 70 | The star average is only one input. We also read volume, velocity, the specificity of review language, and response cadence. Specific reviews are what AI quotes verbatim. | Good |
| Backlink & citation authority | 8 | 73 | Domain authority and editorial quality of the sources that attest to you. | Good |
| Google Business Profile | 8 | 90 | Required and recommended fields; update cadence. The listing AI pulls from first. | Good |
| Speed & mobile | 7 | 30 | Core Web Vitals at the 75th percentile, on a real phone. | Poor |
| Content freshness & schema | 5 | 37 | Crawl recency, intent alignment, valid JSON-LD, canonicals. | Poor |

## How AI decides what to tell you about a post office

When you ask ChatGPT, Gemini or Google about a local business, the AI doesn't visit it. It reads what's already written about it: the business's website, its Google Business Profile, review sites, news stories and directories like this one. Then it repeats what those sources agree on.

That's why AI gets small facts wrong. If Yelp says a place is open Mondays and the website says it isn't, the AI has to pick one. The table above shows the answers that disagree with the record today.

The more sources agree, and the more specific they are, the more confidently AI recommends a business. A review that names who helped and what they did tells an AI far more than one that says "great place."


## How to choose a post office in Massachusetts, with or without AI

A few checks take ten minutes and tell you more than any rating.

- Check that the hours and phone number match on Google, Yelp and the business's own website. Mismatches are how people end up at a locked door.
- Read reviews that name a person and what they did. Vague praise is easy to fake.
- Look for recent reviews and recent posts. A page nobody has touched in a year may not match the business today.
- Ask for the price before you go, and ask what it includes.
- Where the work needs a license, ask whose license it is and look it up with Massachusetts.


## How to read the marks on this page

- Confirmed (solid circle): from a known source. The business website, its Google Business Profile, review sites like Yelp, Healthgrades and RealSelf, a licensing board, or measured by Local AI Registry.
- Visitor submitted (hollow circle): added or corrected by a person, with the date and how they know, like a phone call or a visit.
- AI guess (hollow triangle): what AI engines are saying right now. Nobody has confirmed it.

## Frequently asked questions


### What is AI search optimization for local business?

Getting a business named when a neighbor asks ChatGPT, Gemini, or Perplexity for a recommendation. Some call it AI SEO, some call it generative engine optimization. Traditional SEO fights for ten blue links; this fights for the one answer an assistant says out loud. The AI Score on this page measures the eight signals that drive it.


### What is Local AI Registry?

The public record of how AI sees local business. We score every business we list by one published method, we keep the questions people ask about it in one place, and we never sell rank. Looking up any business here is free.


### How does this page help a business get recommended by AI?

Assistants read public pages before they answer. This one states what the business does, what people ask about it, and what the Record answers, in one place a machine can read. Correcting what is wrong here changes what an assistant repeats next.


### Who writes the answers here?

Registry AI writes the first answer under every question, from the Record and the public sources named beneath it. Neighbors write the rest under pseudonyms. A registered owner can reply as the business, and their reply says so.


### I own United States Postal Service. How do I fix something or rank higher?

Register the page. It is free, it takes about five minutes, and it lets you correct the Record and reply as the business. Nothing on this page is for sale, so the only thing that moves the score is the work.
