DOR Updates Business Licensing Phone Number on 'Update My Business Information' Page

What Changed

Washington's Department of Revenue (DOR) made a small but practical update to its Update My Business Information page. The page instructs businesses on how to update contact information, mailing addresses, new business locations, or changes in business activities, and it directs certain inquiries to the Business Licensing Service by phone.

According to the update record, the phone number listed for reaching a customer service specialist changed:

• Before: 360-705-6741
• After: 360-705-6705

The surrounding guidance appears unchanged: businesses are still directed to call this number when they need help determining whether a change in business location or activity requires filing a new Business License Application.

Why This Matters for Practitioners

On its face, this is a minor administrative correction. But phone number changes like this one have practical downstream effects for CPAs, tax managers, and controllers who maintain:

• Internal knowledge bases or SOPs referencing DOR contact numbers
• Client-facing FAQs or onboarding materials for Washington business registrations
• Saved bookmarks, PDFs, or screenshots of DOR guidance pages

If any of these materials still reference the old number (360-705-6741), clients or staff attempting to call about a business relocation or licensing question could reach a disconnected line, a different department, or simply experience unnecessary friction. Given that this contact point specifically supports businesses trying to determine whether a new Business License Application is required after a location or activity change, delays here could affect timing on filings tied to a physical move.

What the Page Still Covers

For context, the page continues to outline the core update paths:

• Online via My DOR, described as the fastest method
• By paper, using the Business Information Change Form (PDF)

It also reiterates that a new Business License Application may be required specifically when changing a business's physical location address, and calls out an additional consideration: businesses relocating to a city that partners with DOR for licensing may need to submit a new Business License Application as part of that move.

The page also notes that updated account information may be shared with related state programs, including Business Licensing (Business Licensing Service), Unemployment Insurance (Employment Security), and Workers' Compensation Insurance (Labor & Industries) — a reminder that a single update can ripple across multiple state systems.

Recommended Action Items

Given the narrow scope of this change, we recommend a light-touch review rather than a full policy overhaul:

1. Search internal materials for references to 360-705-6741 and update them to 360-705-6705 where confirmed accurate.
2. Verify directly with DOR before updating client-facing documents, since phone numbers and internal routing can change again without extensive public notice.
3. Flag this for staff who handle business relocations or entity changes for Washington-registered clients, particularly if a location change is pending and a call to Business Licensing Service is anticipated.

A Note on Verification

This update is based on a page-content comparison showing the specific text change described above. We have not independently confirmed the new number is currently active or that no further changes have occurred since the source was captured. As always with contact information, a quick verification call or check of the live DOR page before publishing client guidance is good practice.
