New business filings: building a clean lead list
New business filings are one of the few lead sources where you know the exact moment a need appears. A company formed last Tuesday needs a bank account, insurance, payroll, a lease, and a bookkeeper within weeks. The catch is that a raw feed of filings is mostly noise: shelf companies, holding entities, and registrations made by filing services. The work is in the filtering.
Key takeaways
- States post filings 1 to 5 business days after they are filed, so "new" always means "a few days old".
- Florida publishes filings daily; many other states publish periodic snapshots, so their filing dates arrive in batches.
- Remove filing-service and mail-drop addresses before you count or call anything.
- B2B outreach still has rules: calls and texts to a founder's cell phone fall under the TCPA.
What "new" means in a filings feed
A filings feed lists entities first recorded by a state registry within a window: the last day, the last 7 days, or the last 30 days. Two dates matter, and mixing them up is the most common mistake:
| Date | What it is | Why it matters |
|---|---|---|
| Formation date | The effective date the state accepted the entity | Can be backdated, or set in the future on a delayed-effective filing |
| Published date | When the state first published the record | The date your feed actually learned about it |
Florida's Sunbiz publishes daily files, so a Florida filing's published date is the day it appeared. States that publish periodic snapshots instead deliver a month of formations at once; CoverFi uses the formation date for those, capped at the snapshot date so a future-dated filing never shows up as "new" before it exists. Either way, budget for the 1 to 5 business days states take to post a filing.
Filter out the noise before anything else
Run these filters in order. Each one is cheap, and together they usually remove the bulk of a raw list:
- Entity type. Keep LLCs and corporations; drop nonprofits and limited partnerships unless they are your market.
- Filing-service agents. A registered agent named on 25 or more filings in one ZIP is a service, not a founder. CoverFi flags these as "filing service".
- Mail-drop addresses. Any address carrying 1,000 or more registered entities is an agent office or virtual mailbox. Those companies may operate anywhere.
- Geography. Filter by city or ZIP of the principal address, which is where the business says it operates, rather than the state it was formed in.
- Name patterns. Names with "Holdings", "Properties", or a street number are often single-asset vehicles that will never buy an operating service.
For more on reading the fields themselves, the business entity search guide covers status, agents, and officer disclosure by state.
Work the list while it is fresh
The value of a filing decays quickly. A new LLC picks its bank and its insurer early, so a list worked in week six is competing with everyone who worked it in week one. A practical cadence:
- Daily: pull the last day of filings for your ZIPs and apply the filters above.
- Weekly: pull the last 7 days to catch late postings from states that publish slowly.
- Monthly: compare month-over-month counts by ZIP to spot areas heating up. Monthly trend views should end at the last complete month, because the current month is still filling in.
Contact the founder lawfully
A new LLC's filing usually names a person, and the phone number you find for that person is often a personal cell phone. Being a B2B sender does not exempt you from the TCPA: autodialed or prerecorded calls and texts to a cell phone need prior express consent, and telemarketing calls are subject to calling-time limits and Do-Not-Call rules. Email falls under CAN-SPAM, which requires an honest subject line, a physical address, and a working opt-out. The TCPA compliance guide explains consent and calling windows in more depth. General information, not legal advice.
A clean sequence for a new filing:
- Verify the principal is a person, not a filing service.
- Confirm the business address is not a mail drop.
- Prefer email or mail for the first touch.
- Scrub any phone number against Do-Not-Call before dialing, and respect the calling window for that area code.
Frequently asked questions
How quickly do new LLC filings appear?
Most states post a filing 1 to 5 business days after it is filed. Florida publishes daily; states that publish periodic snapshots can lag by weeks.
Why are so many new filings at the same address?
Filing services and virtual offices register thousands of companies at their own address. Filter out addresses with very high entity counts before building a list.
Can I call the person named on a new business filing?
You can contact them, but the TCPA still applies to calls and texts to cell phones, including in B2B outreach, and Do-Not-Call rules apply to telemarketing calls.
