Quick answer
Alliant has multiple eligibility routes and explicitly publishes support for SSN or an unexpired ITIN in its membership path. It also uses a Foundation-based route that can satisfy membership eligibility. The exact path should be identified before starting the application.
Published rules for this service
Alliant lists employer, family and Chicago-area community paths. If none applies, select the Alliant Credit Union Foundation route; Alliant says it pays the one-time $5 membership fee on your behalf. The page also permits applicants living outside the U.S. with an SSN or valid ITIN, subject to application requirements. Alliant has no branches, so an unresolved application uses digital or telephone support.
Decision path
Already eligible by employer/family/community → use that path. No direct eligibility → check the Foundation route. ITIN applicant → follow the current application documentation requirements; ITIN acceptance does not eliminate other identity/residency checks.
What to do next
Prepare the current required identification and eligibility proof. Confirm Alliant Credit Union charter 67955/Chicago identity when using external data or complaint sources.
Important limits
Do not confuse Alliant with another institution of the same name. Do not say Foundation participation guarantees product approval. Do not generalize one documentation route to every applicant.

Eligibility checklist
Identify employer, family, Chicago-community or Foundation eligibility. If using ITIN, follow Alliant’s current documentation for an unexpired ITIN and any other identity requirements. If the Foundation route is used, note that Alliant pays the one-time $5 Foundation joining fee on your behalf; it is not a cash benefit.
FAQ
Who pays the Foundation joining fee? Alliant says it pays the one-time $5 fee on your behalf when you select that route. Can I use a branch to resolve an application issue? Alliant says it has no branches; use its digital support or telephone channel.

Membership eligibility is a separate question from ACH delivery/return rules. After joining, use the Alliant disclosure for the actual account involved.
