How Maine's corporate registry works
Maine's charter number isn't just a number — it's a number and a letter. An entity is filed as 20171072 D, and the D is the filing type. DC is a limited liability company, DP a limited liability partnership, LP a limited partnership, ND a nonprofit under Title 13-B. Foreign entities carry their own codes: F is a business corporation doing business in Maine, FC an LLC. The domestic/foreign split lives inside the identifier instead of a separate column, and BizVerify returns the pair verbatim as jurisdiction_id.
The public Corporate Name Search takes a name keyword — 60 characters — or a charter number, and every hit opens an Information Summary. The Division states there is no fee to view or print that page. It carries the legal name, former, assumed and fictitious names, charter number, filing date, filing type, jurisdiction, status, the clerk or registered agent name and address, and the principal home office address. Paid surfaces sit below it: $3.00 per filing image, $5.00 more to certify an order, and $30 for a Certificate of Existence (Good Standing) on a for-profit entity — $10 on a nonprofit.
Two Maine labels catch people out. A corporation appoints a clerk, not a registered agent — that's Title 13-C's word — while an LLC appoints a registered agent under Title 31, so the summary hedges and labels the block "Clerk/Registered Agent". And Excused is a real status, not a data error. A corporation in good standing that has stopped conducting business can apply to be excused; it then owes no annual reports until it files a Certificate of Resumption.
BizVerify supports instant quick checks for Maine today — legal name, filing type, charter number, status. Deep verification, including the clerk or registered agent record and the principal home office address, is on the roadmap for this jurisdiction.
What Maine specifically charges and requires
Formation
A Maine corporation files Articles of Incorporation for $145. An LLC's Certificate of Formation is $175 — $30 more than the corporation. Qualifying from out of state costs $250 either way. Reserving a name ahead of the filing is $20 and holds it for 120 days. Expedited service is $50 per request for 24-hour turnaround and $100 per request for immediate service.
Annual obligations
Every business and nonprofit entity on file as of December 31 owes an annual report the following year, and Maine runs one statewide deadline: June 1. The first report is due June 1 of the year after the entity was incorporated, formed, or qualified. The fee is $85 for a domestic business entity, $150 for a foreign one, and $35 for a nonprofit corporation. When June 1 falls on a weekend the deadline shifts to the next business day — the announced 2024 date was June 3. File late and a $50 penalty is added to the fee; leave that penalty unpaid and a domestic entity is administratively dissolved while a foreign entity's authority is revoked. Reinstatement runs $150 per ground and is capped at $600 total, however many reports were missed.
Clerk and registered agent
A corporation must keep a clerk; an LLC must keep a registered agent. Appointing or changing either is $35. Losing one — or not reporting an address change — is its own ground for administrative dissolution. An Application for Excuse is $40, and the Certificate of Resumption that ends it is $100.
| Filing / record | Fee |
|---|---|
| Articles of Incorporation | $145 |
| LLC Certificate of Formation | $175 |
| Foreign qualification (corporation or LLC) | $250 |
| Annual report — domestic / foreign / nonprofit | $85 / $150 / $35 |
| Annual report late penalty | $50 |
| Reinstatement after administrative dissolution | $150 per ground, max $600 |
| Certificate of Existence (Good Standing) | $30 for-profit / $10 nonprofit |
| Expedited filing — 24 hour / immediate | $50 / $100 |
Common ways developers use Maine verification
Gate an onboarding agent on live Maine status
An agent takes a Maine company name and calls verify_business({ entity_name, jurisdiction: "us-me" }) over the BizVerify MCP server. Good Standing provisions, Administratively Dissolved and Authority Revoked block, and Excused goes to a human because it means dormant-but-compliant rather than delinquent. The same loop runs unchanged from OpenAI Agents or a CrewAI crew.
Sweep Maine counterparties around June 1
Maine moves on one statewide clock, so a book of customers that looked clean in April can shed entities by midsummer. Run a quick check across every Maine jurisdiction_id you hold in late May, then again in July, and you catch the ones that missed the report before an invoice or a renewal does. An n8n schedule and a list of charter numbers is the whole job.
Reconcile on the composite charter key
Legal names drift; 20171072 D doesn't. Resolve each Maine counterparty to its charter number once, keep the filing-type letter attached, and dedupe on that instead of the display name. The letter also tells you whether you have a domestic corporation or a foreign qualification without a second lookup — which matters when a KYB pipeline has to record where an entity was actually formed.
Qualify Maine leads without the bulk file
Maine sells its corporate records in bulk through the state portal — $600 a month for the full corporate and UCC file, $300 a week for updates. If you only need to know whether a few thousand prospects are real and current, per-call quick checks skip both the subscription and the staleness a monthly drop carries. Score the results straight into lead enrichment.
Frequently asked questions
What does Excused mean on a Maine entity?
It means the corporation asked to stop filing. A domestic business or nonprofit corporation in good standing but not conducting business can file an Application for Excuse ($40) and owes no annual reports until it submits a Certificate of Resumption ($100). Excused is dormant by election, not delinquency — don't treat it the way you'd treat Administratively Dissolved.
Which identifier does BizVerify return for a Maine entity?
The charter number exactly as Maine prints it: digits plus the filing-type letter, like 20171072 D. That pair is the stable key: it survives name changes and it encodes the entity type. D is a domestic business corporation; F is a foreign corporation authorized to do business in Maine. Reconcile on it rather than the legal name.
When is a Maine annual report due?
June 1, statewide, for every business and nonprofit entity on file as of the previous December 31. The first one is due June 1 of the year after formation or qualification. When June 1 lands on a weekend the deadline moves to the next business day. A late report costs an extra $50, and an unpaid penalty leads to administrative dissolution or, for a foreign entity, revocation of its authority.
Does Good Standing mean a Maine business is legitimate?
No. It means the statutory filing requirements have been met with the Secretary of State. The Division says plainly that it does not review or verify the information submitted and does not regulate or investigate business practices or operations. Read Good Standing as "current with the registry", then layer your own diligence on top of it.
How current is Maine entity data?
A quick check reflects the Maine record as it stands when the call runs — there's no nightly snapshot sitting between the source and your response. A status change that just posted shows up on the next check. The trade-off is that p95 latency tracks the registry's own responsiveness.
Does BizVerify support deep verification for Maine today?
Maine is quick check today: legal name, filing type, charter number, and status — enough to confirm an entity exists and where it stands. Deep verification — the clerk or registered agent record, the principal home office address, and the filing date — is on the roadmap for Maine, and we prioritize by demand. Tell us what you need and it moves up.
Do I get charged for a Maine name that doesn't exist?
A confirmed "no match" still counts as a quick check (1 credit, about $0.08 on public pricing) — the lookup ran and proved the name isn't on the Maine register. Hard errors from the registry side, like a timeout, don't consume credits.
