What is a MAST Permit?
A MAST permit is a license to serve and sell alcohol in Washington State. It stands for Mandatory Alcohol Server Training and is only valid in Washington State.
MAST Permit: Key Fact
It’s a document that permits individuals to handle alcoholic beverages in liquor-licensed businesses. It’s often referred to as Class 12 or Class 13 permits, depending on the individual’s age. In Washington State, obtaining a MAST permit is mandatory to be legally employed by an establishment licensed to serve alcoholic beverages. Without it, you risk fines, job loss, or legal action.
Types of MAST Permits
| Type | Age Requirement | Key Duties Allowed |
|---|---|---|
|
Class 13 |
18-20 |
Take orders, serve beer/wine at tables, open bottles |
|
Class 12 |
21+ |
All Class 13 + mix/pour spirits, draw from taps, supervise staff |

Why Do You Need Mandatory Alcohol Server Training?
The purpose of Mandatory Alcohol Server Training is to educate and train alcohol servers on the impacts of alcohol on their customers and to improve the health and safety of the community.
This is explained by the Washington State Liquor and Cannabis Board (WSLCB) as:
"Education of alcohol servers on issues such as the physiological effects of alcohol on consumers, liability and legal implications of serving alcohol, driving while intoxicated, and methods of intervention with the problem customer are important in protecting the health and safety of the public.
The legislature further finds that it is in the best interest of the citizens of the state of Washington to have an alcohol server education program."
Why It Matters:
Proper training reduces DUI incidents (WA saw a 10% drop in alcohol-related crashes post-MAST updates ), minimizes liability lawsuits, and protects your job. For example, knowing how to spot fake IDs prevents underage sales fines up to $500.
How Do You Get a MAST Permit?
If you were just hired, you are required to obtain Mandatory Alcohol Server Training within 60 days of your hire date. To obtain the permit, you must complete the Mandatory Alcohol Server Training from an online or in-person provider.
The easiest and fastest way is an online course like ServeSmart’s mobile-optimized training.

Can I work without a MAST Permit?
Short answer: No, it’s illegal, and the consequences can be severe. While new hires have a 60-day grace period to obtain your Mandatory Alcohol Server Training (MAST) permit, working without a valid one after that window closes exposes you to criminal penalties, fines, and potential job loss. This applies to all roles involving alcohol service, mixing, sales, or supervision in Washington State’s liquor-licensed establishments.
The 60-Day Grace Period: What It Means
- Who qualifies? Only employees newly hired for on-premises alcohol service (e.g., bartenders, servers, managers). You must complete an approved MAST course and exam within 60 days of your start date.
- No grace for certain roles: There’s zero grace period for alcohol tastings, event staff, or off-premises activities like growler filling, permits are required immediately.
- Carry it always: Even during the grace period, keep your ID ready for inspections. Once issued, your physical MAST permit (mailed within 30 days) must be on you at all times.
Failing to comply isn’t just a paperwork oversight, it’s a violation of Washington State law (RCW 66.20.310 and related statutes), enforced by the Washington State Liquor and Cannabis Board (WSLCB). In 2025, enforcement has ramped up with more random audits, especially in high-traffic areas like Seattle and Spokane.
Penalties for Working Without a Valid MAST Permit
Penalties can hit both you (the individual) and your employer, including license suspension. Here’s a breakdown based on current WSLCB guidelines:
| Violation Type | Fine | Jail Time | Additional Consequences |
|---|---|---|---|
|
First Offense (After Grace Period) |
Up to $500 |
Up to 90 days |
Criminal citation; possible employer fine up to $2,000 |
|
Repeat or Tasting/Event Violation |
Up to $1,000 |
Up to 180 days |
Permit suspension; WSLCB administrative action (e.g., business license review) |
|
Employer/Establishment |
Up to $10,000 |
N/A |
License revocation; civil liability for underage/over-service incidents |
Sources: WSLCB FAQs (updated 2025) and RCW 66.20.310. Real-world examples from Washington servers (e.g., Reddit reports) show first-time fines often land around $250–$500, but jail time is rare unless combined with other violations like serving minors.
Why Risk It? The Bigger Picture
Beyond legal trouble, working without a MAST permit leaves you vulnerable:
- Liability exposure: If an incident occurs (e.g., over-serving leading to a DUI), you could face personal lawsuits under dram shop laws.
- Job security: Employers must verify permits, getting caught means immediate termination and blacklisting.
- Career impact: It stalls your path to higher roles like bar manager, where Class 12 certification is essential.
In short, the 60-day window is your only buffer, use it wisely. As of November 2025, WSLCB emphasizes education over punishment, but compliance is non-negotiable for protecting public safety.

Who Issues the MAST Permit?
The MAST Permit is issued by the course provider you took your training through, not WSLCB.
Your course provider is required to submit your information and status of completion to WSLCB as well as mail the permit to you within 30 days of you completing the course. If you do not receive your permit within 30 days, reach out to your provider or contact the WSLCB.
At the end of the course, you will receive a certificate of completion (not to be confused with the permit). You can use this certificate as proof to your employer that you have completed the MAST training.
‼️ Important Note: The course certificate is not a temporary permit, do not use it in place of the MAST permit.
How Long Is a MAST Permit Good for?
MAST permits are valid for 5 years from the completion date of your test. The expiration date is the 1st of the month following the month of the date you took your test. For example: if you completed the course on 10.15.2025, your expiration date would be 11.1.2030.
If your license expiration date is approaching, you should renew it 45 days before the permit expires. Serving alcohol with an expired license is against the law.
If you have turned 21, you’ll need to upgrade your Class 13 permit to a Class 12 permit. To do this, reach out to the provider you received your permit from and request a Class 12 permit.
How Do You Renew Your MAST Permit?
Retake any WSLCB-approved course (online or in-person) at least 45 days before expiration. No exam needed if current.
Since it is against the law to serve alcohol without a permit, it is important to take steps to renew your permit before it expires. To renew your permit, you must retake the Mandatory Alcohol Server Training from ServeSmart or any licensed third-party provider.
📃 Is your MAST permit valid?
Check the status of your permit by using the Permit Checker on the WSLCB website.
The WSLCB keeps a record of all of the permits for five years. For a MAST Permit renewal, it is recommended that you renew your permit at least 45 days before the expiration date.
