# Daytime Phone Number > Daytime Phone Number means the primary contact number provided by a party for communication during standard business hours. **Term:** Daytime Phone Number **Last updated:** 2026-07-29 ## Definition ## What a "Daytime Phone Number" means in a contract A Daytime Phone Number is the telephone number a party nominates as its main point of voice contact during ordinary business hours. It is a practical detail rather than a substantive obligation, but it still earns a place in a contract because reliable, time sensitive communication matters. When something needs to be confirmed, coordinated, or raised quickly during the working day, the Daytime Phone Number tells the other party exactly where to call. ### How the term is defined or measured The term is usually captured in a contact details or notices section rather than in a formal definitions clause. The agreement records the number, identifies whose it is, and sometimes names the individual or role that answers it. "Daytime" is understood as standard business hours in the relevant location, though contracts occasionally state the hours expressly. Because contact information changes, agreements typically require a party to keep its details current and to notify the other of any change. ### Where the term appears Daytime phone numbers appear wherever quick coordination is useful. They are standard in the contact schedules of many commercial contracts and are especially important where continuity and rapid response matter, as in a [business continuity plan](https://www.genieai.co/en-us/template-type/business-continuity-plan), which relies on reachable contacts to activate response steps. They also feature in communications and technology arrangements, such as an [IT and communication systems policy](https://www.genieai.co/en-us/template-type/it-and-communication-systems-policy), which may govern how contact details are recorded, used, and protected. ### Why the exact wording matters Even a simple contact field can carry weight. If the contract treats phone contact as sufficient for certain communications, then an out of date or unmonitored number can cause a party to miss something important, so agreements usually reserve formal notice for writing and use the phone for practical coordination. The wording should be clear that a phone call is not, by itself, formal legal notice unless the contract expressly says so. Contact numbers can also be personal data under the law governing the contract, which affects how they may be stored and shared, so even here privacy considerations apply. ### Drafting considerations - **Keep it in the right place.** Record the number in the contact or notices section and, if it matters, distinguish it from the formal notice address. - **Require updates.** Oblige each party to keep its daytime number current and to notify changes. - **Clarify status.** State whether a phone call constitutes notice, and if not, reserve notice for writing. - **Respect privacy.** Treat contact numbers as data to be handled consistently with the law governing the contract. It can also help to say who is expected to answer the number, whether a named individual, a role, or a monitored line, and whether a voicemail or a call back within a stated time counts as having made contact. These small points matter most in urgent situations, where the difference between a monitored line and an unanswered mobile can determine whether a time sensitive step happens on time. Because a Daytime Phone Number is a generic detail, it rarely needs elaborate drafting, but it should not be neglected either: continuity and coordination both depend on reaching the right person during the working day. Keeping the number current and clarifying that routine calls are not formal notice avoids the small but real problems that arise when a party cannot be reached, or when a casual call is later argued to have been a binding communication. ## Context ### Relevant circumstances - When establishing the primary mode of communication between parties - For use in possible dispute resolution methods ### Relevant sectors - Real Estate - Information Technology - Retail - Healthcare - Telecommunications ## Relevant contract types - [Business Continuity Plan](https://www.genieai.co/en-us/template-type/business-continuity-plan) - [IT and Communication Systems Policy](https://www.genieai.co/en-us/template-type/it-and-communication-systems-policy) --- This is the Markdown representation of [https://www.genieai.co/en-us/define/daytime-phone-number](https://www.genieai.co/en-us/define/daytime-phone-number), provided for AI agents and crawlers.
