If you're trying to reach Massachusetts unemployment by phone, you're looking for the Department of Unemployment Assistance (DUA) — the state agency that handles unemployment insurance claims, eligibility determinations, appeals, and benefit payments for workers in Massachusetts.
The main DUA claimant phone line is:
📞 877-626-6800
This number connects you to the DUA's UI Online assistance line. Hours are typically Monday through Friday, 8:30 a.m. to 4:30 p.m. ET, though hours can change during high-volume periods or state holidays. Always confirm current hours on the official mass.gov/dua website before calling.
For Spanish-language assistance, the DUA also offers support through the same main line. TTY/TDD users can reach relay services through 711.
The DUA phone line handles a range of claimant needs, but not everything can or should be done over the phone. Understanding what the line is actually useful for saves time.
Common reasons claimants call:
What phone agents generally cannot do:
If your claim has a specific issue — like a hold, a pending adjudication, or a disqualification notice — phone agents may be able to flag the issue but typically cannot resolve it on the spot. Those situations often require written documentation submitted through UI Online or through the formal appeal process.
Massachusetts strongly encourages claimants to handle most tasks through UI Online, the state's self-service portal. Many actions that used to require a phone call can now be completed online, including:
Calling makes more sense when you're dealing with a system error, a confusing notice, a login problem, or a situation where the online portal isn't giving you the information you need. If UI Online is showing an unexpected status on your claim, calling can at least clarify what stage the claim is in — even if the agent can't resolve it directly.
Beyond the main claimant line, the DUA has additional contact points depending on what you need:
| Contact Type | Purpose | How to Reach |
|---|---|---|
| Employer line | Employer account and tax questions | 617-626-5075 |
| Appeals line | Hearing scheduling, appeal status | Through UI Online or DUA appeals unit |
| Overpayment unit | Repayment plans, overpayment notices | Accessed through UI Online or mailed notice |
| DUA mail address | Written correspondence, document submission | P.O. Box 338, Lawrence, MA 01842 |
Overpayment and appeals matters in particular tend to move faster when handled in writing — either through UI Online or certified mail — because they create a documented record.
High call volumes are a persistent reality at state unemployment agencies. Massachusetts is no exception. During periods of elevated unemployment — or after major policy changes — wait times can stretch significantly. A few things that may help:
It's worth being clear about the limits of a phone call in the unemployment process. Massachusetts DUA phone agents can provide information and flag issues — but most consequential decisions about your claim go through a separate process.
Eligibility determinations are made by DUA adjudicators who review your separation reason, your work history, and any response from your employer. If your claim is denied or flagged as disqualified, that decision comes with a written notice that includes appeal rights and a deadline — typically 10 days from the mailing date of the notice.
Appeals are handled through the DUA's Hearings Department, not the general phone line. An appeal gives you the right to present your side of the case before a hearing officer. Whether or not to file an appeal — and how to approach it — depends on the specific determination you received, the reason given, and your own facts and documentation.
Whether your situation involves a layoff, a resignation, a discharge, a partial unemployment claim, or a claim that's been sitting in adjudication, the outcome depends on the specific details of your case — your wages, your separation, your employer's response, and how Massachusetts law applies to those facts. The phone number gets you connected. What happens from there is shaped by all of that.
