What people say
I was so excited and pleased with my experience with NSARCO. I had not been to my therapist for my depression in some time. My meds had been working but i still needed comforting as my life had changed. My landlord wanted proof. Thank you so much for a smooth and easy process. Your site was easy with the chat feature. You are my hero.
They are very helpful and their products are good quality. We are waiting for a new updated ID card! Looking forward to sporting his new one on his red saddle bag he wears!!
This website does provide PSA letters quickly after your case is reviewed by a licensed mental health professional, everything took maybe 2 hours.

NSAR has been a service-animal registry since 1995 — long before the “online ESA letter” industry existed. Every letter we issue is signed by a state-licensed therapist after a thorough clinical review of your intake. You can verify their state license number on your state’s public license registry before you pay.
LCSW, LPC, LMFT, licensed psychologist — all in your state, all license-verifiable. Names + credentials published before you pay.

Your intake is encrypted at rest, every PHI access is audit-logged, and our letter discloses that you qualify — not your diagnosis. Built for compliance, not just appearance.
Every review is tied to a verified paid order. We don't write our own reviews — and we don't hide the bad ones.

Emotional Support Animals
An ESA is a companion animal that a licensed clinician determines provides therapeutic benefit for a qualifying mental-health condition. ESA housing protection changed in 2026 — HUD now enforces the Fair Housing Act only for trained service animals, so whether an untrained ESA is protected depends largely on your state’s law.
Common questions
Service Dogs
A service dog is a dog individually trained to perform tasks that mitigate a specific disability — physical or psychiatric. The ADA protects them in restaurants, stores, hotels, planes, and your apartment. The ADA also lets you train the dog yourself.
Want to self-train?
The ADA explicitly permits it. We’ve assembled the foundation curriculum, the public-access self-test, and six task-category playbooks (psychiatric · mobility · guide · seizure alert · hearing alert · medical assist) so you can do it right.
Open the training hub →Rights & Laws
We translate the regulations into plain English so you can actually use them. Each topic links into a deep-dive with citations, the “in plain English” version, and scripts for the disputes that come up.
Housing
Fair Housing Act
What the FHA covers, how HUD's 2026 enforcement change affects untrained ESAs, your state's protections, and the reasonable-accommodation request walkthrough.

Public access
Americans with Disabilities Act
The two-question rule for service dogs in restaurants, stores, taxis, and hotels. ESAs are not covered — that's the line.

Travel
Air Carrier Access Act
Service dogs fly free in the cabin. ESAs are pets on most U.S. airlines after the 2021 DOT rule. The DOT form walkthrough + airline notes.

Training
The ADA does not require professional training — you can train the dog yourself, and many handlers do. We’ll show you the order of operations: foundation manners first, public-access proofing second, task work last. Or if self-training isn’t the right fit, we’ll point you to vetted trainers in your state.
Verify a letter or registration
Look up the registration number on any NSAR-issued letter or ID and we’ll confirm whether it’s authentic and currently active. Free. No login. No data shared back to the customer.
