Colorado CIIS · Public access, corrections and school proof
Find and Verify Your Colorado CIIS Record
The Colorado Immunization Information System Public Portal can provide an available official record for you or an eligible legal dependent. Access works only when the identity and contact information match what participating providers submitted.
Use this guide to choose the correct download, solve an exact-match failure, request a manual copy, correct a missing dose and prepare documentation for school, childcare, camp, college or work.
Privacy first:
This is an independent information guide, not CDPHE or CIIS. Do not enter a verification code, date of birth, photo ID, medical record, portal password or QR code on this page. Submit private information only through the official portal or secure CDPHE request route.

Official online workflow
How to download a Colorado CIIS record
Open the official CIIS Public Portal
Confirm that the address uses the state.co.us domain before entering personal information.
Select “Me” or “Dependent”
Use “Me” for your own record. Use “Dependent” only when you are legally authorized to request that person’s record.
Enter the provider-recorded identity details
Use the exact name, date of birth and gender documented by the clinic, pharmacy or vaccination site.
Choose email or SMS verification
Select an available contact destination connected with the CIIS record and request the access code.
Enter the access code
Check text messages, email, spam and junk folders. Never give the code to an unexpected caller or website.
Select the required record
Download the full record, school certificate, COVID-19 record or COVID-19 QR code according to the recipient’s instructions.
Review every page and dose
Check the patient name, birth date, vaccine types, administration dates and whether expected providers or pharmacies appear.
Save a protected copy
Download the file rather than relying on a cropped screenshot. Keep one printed copy and one protected digital backup.
Browser validation problem:
Enable JavaScript and cookies, use a normal browser rather than an in-app browser, disable aggressive content blockers for the portal and reload the page.
Recently updated contact information:
Colorado’s current myColorado guidance says updated CIIS contact information may take at least 24 hours to become available for portal matching.
Efficient retry rule:
Try the most likely provider-recorded details once. Repeated random attempts are less useful than asking the provider to verify the CIIS profile.

How to access a child’s Colorado record
Select the dependent request
Use this option only when you are authorized to request the minor or legal dependent’s information.
Enter the child’s exact identity
Match the pediatrician, pharmacy or health-system record instead of using a nickname.
Try the parent contact used at vaccination visits
An older family phone number or email may still be connected with the child’s CIIS profile.
Compare the result with provider records
Check whether doses from the pediatrician, pharmacy, school clinic and previous states are present.
Choose the school certificate when appropriate
Ask the receiving school whether it prefers the school certificate or the complete CIIS record.
Use the manual route if the relationship cannot be verified
CDPHE may request identification and supporting documents showing parent or guardian authority.
Pediatrician verification script
“I cannot access my child’s CIIS record. Please verify the child’s exact legal name, date of birth and gender, confirm the parent phone number or email attached to the record, and check whether every vaccine your office administered was accepted by CIIS.”
No exact match or multiple profiles
Fix a CIIS Public Portal access problem
Former name mismatch
Try a maiden name, previous surname, suffix or hyphenated spelling used during the vaccine visit.
Old contact details
The available verification code may be linked to a former phone number or email.
Birth date or gender differs
Ask the provider to compare its patient profile with the information submitted to CIIS.
More than one record appears
Vaccinations may be divided between duplicate profiles that need provider or CIIS review.
The vaccine was never reported
The dose may remain only in the provider, pharmacy, employer or hospital record.
The vaccination occurred elsewhere
An out-of-state, military, tribal, federal or international vaccination may not appear automatically.
A prior opt-out was submitted
CIIS may no longer contain the removed information.
Older paper-only record
Family files, former schools or archived providers may be the only remaining source.
Use the official help form in this order
Verify your details one final time
Compare them with the provider portal, pharmacy account or insurance profile.
Open the Immunization Record Information Request Form
The form is intended for people having difficulty accessing their own or a minor child’s record.
Select the correct request type
Choose your own record, a minor child’s record or the appropriate listed access route.
Select the actual problem
Current choices include “We didn’t find an exact match,” “More than one immunization record was found” and another issue.
Submit only one form
The official form warns that duplicate submissions increase response delays.
Watch for a secure email
CIIS Help Desk staff follow up at the email address entered in the form.
Use CDPHE’s current Request to Release Immunization Record Form when public access remains unavailable. Download a fresh copy immediately before completing it because form requirements can change.

Fix a missing, incorrect or duplicate vaccination record
A missing portal dose does not prove the vaccination never occurred. The administering organization is normally the best source for verifying clinical information.

Provider correction script
“My CIIS record is missing or incorrectly showing the [vaccine] administered at your location around [date]. Please verify the original administration record, the identity details submitted and whether the dose was rejected, not reported or attached to another CIIS profile.”
New dose timing:
Colorado’s current myColorado guidance recommends allowing approximately 24–72 hours for a newly reported vaccination to appear.
Do not edit the official PDF or guess a date.
A valid correction should come from a source that can verify the clinical administration record.
2026–27 school documentation
Colorado immunization records for K–12 school
Seventh-grade Tdap change:
Beginning with the 2026–27 school year, Colorado requires an adolescent Tdap dose before the student’s first day of seventh grade.
A seventh-grade student may already meet the requirement when the school has a record showing an adolescent Tdap dose administered on or after the tenth birthday.

Mixed documentation
A record, catch-up plan and exemption may cover different vaccines.
Ask which exact vaccine or document remains unresolved.
School nurse script
“Please identify the exact vaccine, dose or document missing from the student’s file. Do you accept the CIIS School Certificate, and does the student also need a provider-signed in-process plan or Colorado exemption certificate?”
Attendance consequence:
Colorado states that a student without the required record, in-process plan or exemption documentation must be denied attendance in accordance with applicable law.
Uses the state medical or nonmedical exemption process.
A copy must be provided to each school or childcare program attended.
CDPHE does not retain a usable copy for the family.
The certificate can expire or require resubmission depending on the setting.
CIIS opt-out
Removes the person’s immunization information from CIIS.
Does not create a school vaccine exemption.
CDPHE recommends downloading the record first.
The family becomes responsible for preserving all records.
Rescinding later may require a provider to re-enter available history.
Permanent-record warning:
CDPHE says immunization information is permanently deleted when an opt-out is processed. Download and verify the record before submitting an opt-out form.
Nonmedical module tip:
CDPHE advises using a desktop or laptop rather than a mobile phone or tablet because the online education module and electronic certificate may not function correctly on mobile devices.
CIIS-generated record or accepted provider documentation.

Interstate exchange is not a guarantee:
Colorado exchanges some registry data with selected states, but individual doses may still require a separate provider or registry request.
Use CDPHE’s county directory and call before visiting because record services and appointment rules vary.
CIIS Help Desk script
“I am trying to access the CIIS record for [myself or my minor child]. The portal displayed [no exact match or multiple records]. I checked the legal name, birth date, gender, previous phone numbers and emails. Which secure request or correction route should I use?”
How do I get my Colorado immunization records online?
Use the official CIIS Public Portal. Choose whether the record is for you or a legal dependent, enter the identity information exactly as documented by the healthcare provider, receive an email or SMS access code and download the available record.
Can I get my child’s Colorado immunization record?
A parent or legal guardian can use the dependent option in the CIIS Public Portal. The child’s name, date of birth, gender and associated parent contact information must match the CIIS record. Manual requests may require identification and relationship documentation.
Why does the CIIS portal say no exact match was found?
The name, date of birth, gender, phone number or email may differ from the provider-submitted information. Other causes include a former surname, duplicate profile, unreported vaccination, prior CIIS opt-out or an out-of-state vaccination.
What can I download from the CIIS Public Portal?
The current portal workflow can offer a full immunization record, school certificate, COVID-19 record or COVID-19 QR code. Select the document requested by the school, childcare program, camp, college, employer or healthcare organization.
What should I do if a vaccine is missing from CIIS?
Contact the healthcare provider, pharmacy, clinic or public health agency that administered the vaccine. Ask it to verify the clinical administration record and determine whether the dose was not submitted, rejected or attached to a duplicate patient profile.
How do I request a Colorado record when the public portal does not work?
Use the official CIIS Immunization Record Information Request Form for portal-access problems. For a formal manual release, download the current Request to Release Immunization Record Form from CDPHE and include the required identification and supporting documents.
What is the Colorado Tdap requirement for the 2026–2027 school year?
Beginning with the 2026–2027 school year, Colorado requires one adolescent Tdap dose before a student’s first day of seventh grade. A qualifying dose administered on or after the tenth birthday, an approved in-process plan or a valid exemption certificate may satisfy the applicable documentation route.
Can I save my CIIS record in myColorado?
Yes. Download the latest PDF from the CIIS Public Portal and upload it manually to myCards and Documents in myColorado. The direct vaccination-record feature is currently unavailable, and manually uploaded files do not update automatically.
What happens if I opt out of CIIS?
CDPHE says immunization information is permanently deleted from CIIS when an opt-out is processed. Opting out is not a school vaccine exemption. If the opt-out is later rescinded, a healthcare provider may need to re-enter the available history.
How do I find Colorado record help by phone?
The CIIS Help Desk currently lists 303-692-2420 and cdphe.ciis@state.co.us for CIIS assistance. Published hours are Monday through Friday from 7 a.m. to 3 p.m., excluding Colorado state holidays.
