How to look up New Mexico business entity information

New Mexico's business entity database is available through the Secretary of State's online portal, officially known as SOS Enterprise (SOSE). This free search system delivers the four data points needed for onboarding, compliance verification, and business transactions: entity name, entity type, Business ID, and formation date. Below is a walkthrough of how to search the database, where to find each piece of information, and what format each data point takes in New Mexico's system. We'll also cover the state's delayed effective date rules, which can create two distinct dates for recently formed entities.

How to search for New Mexico business entities

Navigate to New Mexico's Business Search portal at enterprise.sos.nm.gov/search/business and enter your search term. You can search by entity name or Business ID. The search tool generally works best if you enter at least a few characters and include any special characters that appear in your entity's name.

The portal is also useful when forming new LLC entities or checking name availability before formation.

Click your entity's row in the results grid to open a side drawer with additional business information, including a View History button for accessing all historical filings.

What you'll see in search results

Results display in a grid format showing key entity information. Clicking View History within the side drawer provides access to all historical filings for the entity.

Newly formed or recently amended entities may not appear in search results immediately, as processing and posting times can vary.

How to find your entity number in New Mexico

Your New Mexico entity number, officially called the "Secretary of State Business ID Number," serves as your unique identifier in the state's business filing system. This identifier is distinct from the NM Taxation and Revenue Department's Business Tax Identification Number (BTIN) and the federal EIN; all three appear as separate fields on NM TRD Form ACD-31015 (Rev. 8/30/2024).

Where to locate your New Mexico entity number

1. New Mexico business search (fastest method)

• Located: Displayed in search results and within the entity side drawer

• Labeled as: "Business ID"

2. Certificate of Organization/Incorporation

• Usually at the top of the document, stamped or endorsed by the New Mexico Secretary of State

New Mexico entity number format

The precise Business ID format is not published on official SOS resources, and IDs may vary in length. A Business ID may appear as a numeric string such as 0008058504, but New Mexico does not publish an official fixed format for this identifier. To confirm your entity's Business ID, search the portal or contact the New Mexico Secretary of State's Business Services office at business.services@sos.nm.gov or via the SOS Business Services page.

How to find your entity type in New Mexico

New Mexico recognizes a broad range of business entity types, including LLCs, business corporations, professional corporations (PCs), nonprofit corporations, limited partnerships (LPs), limited liability partnerships (LLPs), and cooperative associations. The complete list with available filing forms is published on the SOS Enterprise forms page. Entity names must include the appropriate legal designator; for LLCs, the name must contain "limited liability company," "LLC," or "L.L.C." as required by the New Mexico Limited Liability Company Act (NMSA 1978, Section 53-19-3). For corporations, the name must include "corporation," "company," "incorporated," "limited," or an accepted abbreviation under the Business Corporation Act (NMSA 1978, Section 53-11-7).

How to find your formation date in New Mexico

Your formation date appears in New Mexico business search results and on your Certificate of Organization or Incorporation. In the portal, the field is labeled "Initial Filing Date."

Where your New Mexico formation date appears

3. Filing confirmations

Formation date vs. effective date

New Mexico law allows entities to request a delayed effective date that differs from the filing date. For LLCs, New Mexico adopted the Revised Uniform Limited Liability Company Act (RULLCA) via HB 0180 (2017). Under RULLCA as codified in NMSA 1978, a record filed with the Secretary of State may specify a delayed effective date not more than 90 days after the date the record is filed. For business corporation transactions such as mergers, amendments, and restated articles of incorporation, the Business Corporation Act caps the delayed effective date at 30 days after delivery to the SOS (NMSA 1978, Chapter 53). If no delayed effective date is specified, the default is the date and time of filing by the Secretary of State. For internal onboarding and tracking within Discern, use the filing date shown as "Initial Filing Date" in the portal rather than any later delayed effective date.
