*Account checks say whether an account exists. They never say whose it is.*


The LinkedIn check indicates whether a LinkedIn account is associated with a phone number from the United States or India. It runs in bulk jobs only and answers `registered: true`, `false` or `null` (unknown) per number, with the time of the check. It never returns profiles, names, job titles or employers.

## What does the LinkedIn check tell you?

It tells you whether a US or Indian phone number is linked to a LinkedIn account. LinkedIn is Microsoft's professional network (Microsoft completed the acquisition in December 2016). Members can add a phone number for sign-in, account recovery and two-step verification. Most people join with an e-mail address, and the number is optional.

- `registered: true`: a LinkedIn account is associated with the number.
- `registered: false`: a conclusive "no". Common, because many members never add a number.
- `registered: null`: no conclusive answer. Not charged.
- `status: unsupported_country`: the number is not from the US or India. Not charged.

Of the social checks in the catalog, this is the only one limited to these two markets. Coverage outside them is not offered, because we only sell a check where conclusive answers are available at a useful rate.

## Who uses it, and why?

The LinkedIn check is mainly a **B2B lead-verification** signal. When a sales team receives a US or Indian lead through a demo request or event sign-up, a number with a LinkedIn account behind it is more likely to belong to a working professional than to be a typo or a throwaway number.

- **Lead scoring for inbound forms.** Run consented leads through a nightly job and add the result as one scoring input. Pair it with the [US carrier lookup](/services/us-carrier-lookup) or the [carrier lookup](/services/carrier-lookup) to see whether the line is mobile, fixed or VoIP. See [lead verification](/use-cases/lead-verification).
- **CRM hygiene.** Bulk-check contact numbers you already hold for existing business relationships to spot dead entries.

For addresses rather than numbers, use the [LinkedIn e-mail check](/services/linkedin-email-check). It has no country limit and also runs in bulk.

## What do you get back?

Each number gets one result under `checks["linkedin.registered"]`, with no extra attributes.

| Field | Type | Meaning |
|---|---|---|
| `registered` | boolean or null | `true` account associated, `false` none, `null` unknown |
| `status` | enum | `completed`, `pending`, `unknown`, `unsupported_country` or `failed` |
| `confidence` / `confidence_score` | enum / 0–1 | How sure the answer is |
| `checked_at` | timestamp | When the answer was obtained |
| `cached` / `billed` | boolean | Served from cache; charged or not |
| `reason` | string or null | Why an answer is not conclusive, e.g. `UNSUPPORTED_COUNTRY` |

## How is it billed?

You pay the bulk price per number, only for conclusive answers. You're not charged for inconclusive results (unknown, unsupported country, timeout, invalid, duplicate). A mixed international list therefore costs nothing for its non-US, non-Indian rows. The free `POST /v1/jobs/estimate` counts them under `unsupported` and shows the maximum cost. See [pricing](/pricing).

## What are the limits?

- Bulk only: `POST /v1/jobs`, up to 50,000 numbers and e-mails per job, and at most 100,000 numbers × checks. `POST /v1/lookup` answers `403 service_disabled`.
- Countries: US and IN only.
- Requests that look like sequential number ranges or generated e-mail lists are rejected.
- A daily cap per account applies (`GET /v1/limits`). Job data is kept for 30 days by default.

## How do I use it responsibly?

Business contacts are still people with privacy rights. Check only leads and contacts you have a lawful basis to process. Don't use the answer to add numbers to cold-outreach lists. Never try to match numbers to profiles: we don't support it, and our [acceptable use policy](/legal/acceptable-use) forbids profiling and unsolicited messaging. People can object at [/opt-out](/opt-out).

## Example request

See [test mode](/docs/test-mode) and [bulk jobs](/docs/bulk-jobs). The test numbers work here even though they are UK numbers.

```bash
curl https://api.mobilevalidate.com/v1/jobs \
  -H "Authorization: Bearer $MOBILEVALIDATE_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: linkedin-demo-001" \
  -d '{"numbers": ["+447700900001", "+447700900002", "+447700900003"], "checks": ["linkedin"]}'
# then: GET /v1/jobs/{id}?wait=30 and GET /v1/jobs/{id}/results
```

Result row (excerpt, test mode: the first item of `data` from `GET /v1/jobs/{id}/results`):

```json

## Frequently asked questions

### Which countries does the LinkedIn check cover?

United States (+1 numbers assigned to the US) and India (+91). Numbers from any other country come back as unsupported_country and are not charged.

### Can I run it in real time during a form submission?

No. The LinkedIn check runs in bulk jobs only (POST /v1/jobs). For an instant signal during a sign-up, combine real-time checks such as the carrier lookup instead.

### Do I get the person's LinkedIn profile, job title or employer?

No. The check only indicates whether a LinkedIn account is associated with the number. No profile URL, name, photo, job title or employer is returned, and we never enrich leads with profile data.

### Is there a LinkedIn check for e-mail addresses?

Yes. The separate linkedin.email service checks an address and runs in bulk jobs only. It does not have the phone check's country limit.

### Can a test key check non-US numbers?

Yes. In test mode the documented test numbers (+44 7700 900xxx) work for every service, including country-limited ones. Other non-US, non-Indian numbers answer unsupported_country, as they do in live mode.
