What is the difference between COUNT() and COUNT(Id) on Contact?

`COUNT()` returns a single scalar total and cannot be combined with other selected fields. `COUNT(Id)` is an aggregate function, so it can sit next to `GROUP BY` columns - use it whenever you want counts broken down by LeadSource.

Does a COUNT() query on Contact hit governor limits?

`COUNT()` does not return rows, so it does not consume the 50,000-row query limit in Apex the way a full `SELECT` would. It still counts as one SOQL query against the per-transaction query limit.

Why is my contact count different from the report total?

Reports apply their own filters, record-type scoping, and sharing rules. A SOQL count run as an admin sees every record the admin can access, which is frequently a larger set than a filtered report.

SOQL Query to Count Contacts in Salesforce

Copy-paste SOQL to count contacts in Salesforce, with variants for filtered counts, COUNT(Id) vs COUNT(), and grouped totals.

Updated 2026-09-09

You need a number, not a list: how many contacts exist in this org, and how many of them match a filter. COUNT() answers both without pulling a single record into memory.

Contact records are the usual home of duplicate and data-quality problems because they arrive from forms, imports, and integrations at once.

The query: count all contacts

COUNT() returns a single row with the total. It is the cheapest way to size an object before you export or mass-update it.

Count every contact

SELECT COUNT() FROM Contact

Count with a filter

Add a WHERE clause to scope the count. This is the query to run before any data operation, so you know exactly how many rows you are about to touch.

Contacts created in the last 30 days

SELECT COUNT() FROM Contact
WHERE CreatedDate = LAST_N_DAYS:30

Count contacts grouped by LeadSource

COUNT(Id) plus GROUP BY gives you a breakdown in one call. Note the alias - aggregate columns are returned as expr0 unless you name them.

Breakdown by LeadSource

SELECT LeadSource, COUNT(Id) total
FROM Contact
GROUP BY LeadSource
ORDER BY COUNT(Id) DESC

Common mistakes to avoid

Use the API name Contact, not the UI label - the two differ on several standard objects.
Wrap literal text values in single quotes; date literals such as LAST_N_DAYS:30 must stay unquoted.
Run the query in a sandbox first if it feeds a bulk update - a WHERE clause that is one character off can select the whole table.
COUNT() takes no field and returns one row; COUNT(Id) is the aggregate form you need whenever you also GROUP BY.
Counts respect sharing when run as a non-admin user, so two people can legitimately see different totals.

Run it faster with TurboKit

Counting is usually step one of a bigger job - export, cleanup, or a mass update on those contacts.

TurboKit's AI SOQL builder lets you describe the result you want in plain English, returns the query, and exports the rows to CSV or Excel in the same panel - without leaving the Salesforce tab you are already on.
