Oath Discount Codes
Contact: Oath Research and This Site
Two different contacts matter here, and they go to two different places. Questions about an order, a shipment, a return, or a product go to Oath Research directly — this site cannot look up an order, issue a refund, or change a shipping address, because it does not have access to Oath Research's order system. Questions about this page itself — a code that looks wrong, a dead link, or something that doesn't match what Oath Research's own pages currently state — go to this site.
Below: Oath Research's published phone number and address, and how to flag something on this page that needs a second look. Neither contact route decides whether a discount code works — that is checked separately and shown with a date on the home page, not decided by anyone reachable through either contact method below.
Reach Oath Research Directly
If your concern is about an actual order, contact Oath Research. That includes a missing shipment, a return, a billing problem, or testing results for a particular product. Oath can handle those matters. Its published US phone number is +1 480-999-1097. Its physical street address is 51 West Vaughn Avenue Suite 205, Gilbert, Arizona 85233. You can find both details on oathresearch.com, and outside business directories confirm them too.
You must create an account to send a message through Oath's contact form. You do not need an account to use the phone number. This page gives no exact window for staffed hours. Oath's about and contact pages list two different ranges. Staffed weekday hours is the accurate description. Oath generally says it responds to support requests in 24 to 48 hours.
Reach This Site
This site does not sell anything, does not process orders, and cannot look up an Oath Research order, refund, or shipment — that all goes through Oath Research directly, using the contact above. What this site can act on is its own content: a code that no longer works and needs moving to the expired table, a figure that no longer matches what Oath Research's own pages currently state, or a broken link.
There is no live chat and no phone line for this page specifically; it is a small, single-purpose site, not a support desk. Reports about outdated information are useful precisely because a code log is only as good as its last check, and a reader flagging a stale entry is often faster than this site's own next scheduled check.

Copy either code above, then paste it into the discount field at checkout. The 20% code is for first orders; the 15% code works every time.
