Lately, we’ve seen a steady rise in requests for Document Authentication Numbers (DANs) on-site and building development plans, often referred to as SDPs, submitted to the City of Denver. If you work in construction, architecture, real estate investment, development finance, or any other industry that involves development plans. You’ve likely encountered this requirement — and the confusion that comes with it.
Many professionals assume that a standard notarization or even Remote Online Notarization (RON) will meet the city’s criteria. However, the compliant solution for documents requiring a Document Authentication Number (DAN) is In-Person Electronic Notarization (IPEN). IPEN is often referred to as eNotary.
At Denver Mobile Notary Services, we assist professionals engaged in these development projects, such as contractors, architects, real estate companies, and financial institutions, by offering a suitable notary service that delivers quick, mobile IPEN services in Denver.
In this article, we’ll explain:

What Is a Document Authentication Number (DAN)?
A Document Authentication Number (DAN) is a unique, traceable code that a commissioned Colorado eNotary affixes to a document from a pre-issued batch provided by the Secretary of State. This occurs during a qualified electronic notarization, such as IPEN (In-Person Electronic Notarization). This DAN is digitally attached to the notarized document and serves as official proof that the notarization was done in compliance with Colorado Secretary of State regulations.
In Denver, DANs have become especially important. The City of Denver now requires a DAN on many site and building development plans (SDPs), especially those submitted for permits, zoning, or design approvals. Without a DAN, your documents could be rejected or delayed, costing you time and potentially money on your project timeline.
Confusion often occurs: clients frequently call asking for an eNotary or eNotarization for development documents. However, they’re not always aware that not all eNotary services are created equal. A traditional pen-and-paper notarization does not provide a DAN, and even Remote Online Notarization (RON) may not meet City of Denver requirements depending on the document type.

To have a valid DAN affixed to your document, you need a licensed eNotary who is commissioned to do IPEN notary work in Denver—someone who can notarize the document in person using secure, digital technology. This is what makes IPEN different: it combines the convenience of electronic notarization with the legally required personal presence, ensuring full compliance with city regulations.
At Denver Mobile Notary Services, we specialize in IPEN and eNotary services for construction, real estate, financial professionals, and those industries that require this service. We make meeting the City of Denver’s documentation standards easy — no confusion, no delays.
Why Denver Development Projects Now Require DANs
If you're submitting paperwork for a site or building development (SDP) project in Denver, you may have recently been told that your notarized documents must include a Document Authentication Number (DAN). This shift has caused confusion for contractors, engineers, architects, and even real estate investors, especially those unfamiliar with electronic notarization or the difference between eNotary, IPEN, and RON services.
The City of Denver approval requirements have evolved in response to growing concerns about fraud prevention, document traceability, and verification efficiency. When a document includes a DAN, city officials can easily confirm that the notarization was completed by a commissioned Colorado eNotary using secure, approved technology. This streamlines internal processing, eliminates doubt about authenticity, and brings consistency to Denver’s development review system.
Most commonly, DANs are now being required for:
Site development plans (SDPs)
Building development plans
Zoning applications
Infrastructure submissions
Utility approvals
And possibly more, always inquire with the city department if a DAN is necessary for your document
While traditional notarization methods (ink signatures and stamps) are still valid in many cases, they do not provide a DAN. Even Remote Online Notarization (RON) isn’t always accepted, depending on how the City of Denver interprets personal appearance or document type. This has led to rejected submissions, delayed approvals, and frustrated professionals.
That’s why city departments increasingly recommend working with an eNotary in Denver — someone who can perform an eNotarization in person, using compliant technology that facilitates the notarization process, during which the notary affixes a Document Authentication Number (DAN) assigned from a batch provided by the Colorado Secretary of State. It’s not just a technicality; it’s often the only way to ensure your documents are accepted without issue.
At Denver Mobile Notary Services, we stay ahead of these evolving standards so you don’t have to. Whether you're a contractor or a real estate firm, we provide IPEN (eNotary) services tailored to meet the City of Denver’s requirements, helping you move your project forward without delays.
The Problem with Standard Notarization or RON
Many professionals assume that any notarization will get the job done when it comes to site and building development plans in Denver. But if you’re submitting paperwork requiring a Document Authentication Number (DAN), using standard notarization or Remote Online Notarization (RON) can create unexpected setbacks.
Let’s break it down:
Standard Notarization (Paper and Ink)
Traditional notarization — done with a pen, paper, and ink stamp — is valid for many documents. However, it does not use a DAN, which is now required for specific submissions to the City of Denver. This method lacks the digital tracking and authentication features that modern systems demand. That means even if your document is otherwise correct, it could be rejected simply because it doesn’t include a verifiable Document Authentication Number.
Remote Online Notarization (RON)
RON allows documents to be notarized over a secure video platform — and while it’s convenient, it may not always be accepted for Denver’s development documents. Some city departments still require in-person notarization for certain applications. This can cause confusion, particularly when clients search for an eNotary in Denver and assume all digital options are the same.
The truth is, not all eNotary services are created equal.
The Solution: In-Person-Electronic Notarization (IPEN or eNotary)
The only notarization method that fully satisfies City of Denver requirements for DAN-compliant documents is In-Person Electronic Notarization (IPEN or eNotary). With IPEN, the signer appears physically in person, but the notarization is completed electronically, using approved software on a tablet to complete the notarization, during which the notary public, authorized to perform IPEN, affixes a DAN from their assigned batch issued by the Colorado Secretary of State.
That’s why more professionals — from architects to construction consultants — are turning to an experienced IPEN enotary in Denver to ensure their documents are compliant the first time.
At Denver Mobile Notary Services, we specialize in IPEN for development documents, eliminating the guesswork and helping you avoid costly delays.
Why IPEN Is the Ideal Solution
If you're navigating City of Denver requirements for site or building development plans, one notarization method checks every box: eNotary, IPEN, or In-Person Electronic Notarization.
Unlike standard notarization or Remote Online Notarization (RON), IPEN is the only method that combines the in-person presence required for many city documents with the digital technology needed to place a Document Authentication Number (DAN) on your document. It’s a hybrid solution designed to meet today’s evolving notarization and documentation standards, especially for construction, zoning, and infrastructure filings.
What Makes IPEN the Ideal Choice?
Meets City of Denver's eNotary regulations: IPEN fully complies with Colorado Secretary of State guidelines and satisfies local departments requiring physical presence and electronic documentation.
Includes a DAN Assigned by the Notary: During an IPEN session, the notary assigns a secure, verifiable Document Authentication Number (DAN) from a batch issued by the Colorado Secretary of State, giving the City of Denver a quick way to validate your notarized paperwork.
Faster Document Submission: No scanning, mailing, or waiting for hard copies. IPEN allows for immediate digital delivery of notarized documents — a significant win when you're on tight project deadlines.
Protects Against Rejection: Since some city departments do not accept RON and reject paper notarizations without a DAN, IPEN provides a reliable, forward-compatible notarization process that reduces your risk of delays.
