About this data

7counties
23rdby size in this category

The largest concentration is in Baltimore: 2 of 10 (20%). Other cities covered include Annapolis (1), Bethesda (1), Ellicott City (1), Frederick (1), Gaithersburg (1), and 3 more.

By county, the 10 entries fall across 7 counties; the largest are Anne Arundel (2), Baltimore (2), Montgomery (2), Charles (1).

These 10 entries come from a register that publishes no listing dates at all. For those, the only thing that can honestly be said is that the facility appeared in the state register when it was last refreshed, on September 22, 2026. No issue, renewal or expiry date is shown for them, and none is guessed.

All 10 hold the same class of listing: TSA enrollment center, in the source's own wording.

10 of the 10 (100%) hold more than one class of listing. Each is one entry here, with every class it holds shown in its record detail. Across this page the classes held include HazMat endorsement (HME) (10), TWIC (10).

10 have a website. Phone numbers are normalized to one format here; the registers publish them several different ways.

This list publishes no phone numbers, so no listing drawn from it shows one. That is how the source publishes it, not a gap in this record.

The map positions come from the register itself rather than from an address lookup. No distance claim is made anywhere in this text; the "nearest to me" list computes straight-line distances in your own browser from your own location.

Maryland ranks 23rd of the 40 states covered in this category, holding 2% of the listings, ahead of 17 others.

For a wider choice, the largest states in this category are California (50), Florida (47), Texas (43). They are ordered by how many entries each holds, not by how close they are.

Every record on this page comes from Enrollment center locator, published by Transportation Security Administration (enrollment by IDEMIA) on tsaenrollmentbyidemia.tsa.dhs.gov as dataset locator. Each card carries the date the record was last re-checked.

Maryland: questions

Which cities in Maryland have centers?
By count: Baltimore (2), Annapolis (1), Bethesda (1), Ellicott City (1), Frederick (1), Gaithersburg (1), Glen Burnie (1), Salisbury (1), Waldorf (1). Addresses, listing class and, where the register publishes them, listing dates are in the list above.
Are these centers currently licensed?
The state register these records come from publishes no listing dates, so the honest answer is narrower than it looks: each of these 10 facilities appeared in the register when it was last refreshed, on September 22, 2026. No expiry date is shown because none is published, and none is guessed. Confirm the current position with the facility or the issuing authority before relying on it.
Why does one address hold several licenses?
Because a row in the state register is a license, not a business. 10 of the 10 entries on this page hold more than one class at the same address, typically an inspection license alongside a repair or dealer license. They are merged into a single entry here, keyed on the facility rather than on the license, so one shop is one listing and its other classes appear on its own page.
Why do the cards not show star ratings?
No public rating has been matched to any of these 10 records, so no stars are shown. The listing record is the stronger signal in any case: where the register publishes them, the issue date, last renewal, expiry and the enrollment location id all come from the issuing authority, which is not true of a star average.

Report a correction

A listing closed, moved or missing? It gets checked against the source

Something wrong on this page?

These records come from state registers and the registers are not perfect. If a listing is closed, has moved, or the license details do not match what the state told you, say so and it gets checked against the source.

Get told when the register changes

Licenses lapse and get renewed constantly: in the current data nearly a quarter of the records in one state register have already expired. We re-check the registers and email a short summary of what moved.

One email when the register data is refreshed or a rule changes. No more than monthly.
