SMS Terms & Opt-In

Opzaco Worker Authentication SMS— a transactional messaging program operated by Opzaco for property managers (“customers”) and the workers and supervisors they invite to the platform.

Opzaco uses a manager-mediated opt-in flow. Workers do not text a keyword to subscribe. Instead:

1. A worker provides their mobile number to their employer (the Opzaco customer) for the explicit purpose of using Opzaco.
2. The manager signs in to https://opzaco.com/staff and enters the worker’s number into the staff invitation form. Before submitting, the manager checks an attestation confirming the worker has given permission to receive authentication SMS from Opzaco at that number.
3. Opzaco records the attestation (manager identity, worker number, timestamp) and sends a one-time welcome SMS containing a sign-in link.

Workers can review this page at any time at https://opzaco.com/sms-terms.

Below is a faithful, non-interactive preview of the form a manager fills in to invite a worker. The checkbox is required — the manager cannot submit the invite without attesting that the worker has given permission. The attestation, manager identity, and timestamp are recorded server-side as the consent record.

The exact string presented to the manager next to the required consent checkbox, reproduced here for carrier and auditor review:

“I confirm this worker has given me permission to enter their phone number and to receive authentication SMS from Opzaco (a one-time welcome link plus sign-in passcodes). Program details: opzaco.com/sms-terms.”

• Welcome message (one, on invite): a personalized sign-in link to claim the account.
• One-time passcodes: a numeric code when the worker initiates a sign-in attempt.

Opzaco does not send marketing, promotional, or recurring informational SMS. All messages are strictly transactional and authentication-related.

• Welcome:“Opzaco: Maria added you to Sunset Property Mgmt. Sign in: https://opzaco.com/i/AbC123. Account/auth msgs only. Msg frequency varies. Msg & data rates may apply. Reply HELP for help, STOP to opt out.”
• OTP:“Opzaco: your sign-in code is 123456. Reply STOP to opt out.”

Message frequency varies based on how often the worker signs in. Typical activity: one welcome message per invitation, plus a one-time passcode each time the worker initiates a sign-in (usually a few times per week).

Reply STOP to any Opzaco SMS to immediately opt out of all further messages. Workers can also ask their manager to remove their account, which deletes the account and stops all further messages.
