Short answer: yes — start today. You don't need to wait for your Anchor Journals to begin training.
Why you can start now
Your Training Blueprint and daily routines are available in the app as soon as your account is set up. The training itself happens on paper, and any notebook works: write your entries there, follow the routine walkthroughs in the Training library, and log your training in the iOS app as usual. When your Anchor Journals arrive, you simply continue in them — nothing about your practice changes and nothing is lost.
When your journals will arrive
ENCODED Activation includes a 3-pack of Anchor Journals that ships as soon as you enroll, free to the 33 countries we ship to. Depending on where you live, delivery can take up to 2–3 weeks. You'll receive a tracking email from [email protected] when your shipment leaves the warehouse, and you can follow its status anytime in Shipment History on the web or Your Journal Shipments in the iOS app. For the full detail, see When Will I Receive My Physical Anchor Journal?
If you're on Digital membership
Digital is the train-from-anywhere tier: it doesn't include recurring journal shipments, and you use your own notebook by design. After your Activation 3-pack, journals only keep arriving if you switch to Core in My account on the web. See Digital vs. Core: Which ENCODED Membership Is Right for Me?
Bottom line: start your daily training now with whatever notebook you have. Your journals are on the way, and your practice carries straight over the day they arrive.
