Mobile RDD is a sample consisting of randomly generated numbers within thousand series blocks dedicated to providing cellular service. Our multi-source mobile database allows you to save time during fieldwork by connecting you directly to the consumer. Sample Solutions is able to filter RDD sample using a dialer to pulse the raw mobile sample in order to ensure working numbers. Additionally, through provider lookup we can determine if the mobile phone is active and whether it is located in the targeted area. Utilize dual-frame sampling to access a more representative sample of households, reduce bias, cover a larger audience, and increase response rate.
Random Digit Dialing, commonly known as RDD, is a cost effective method for generating a representative sample of households with fixed landlines. When generating your sample, we provide you with access to listed and non-listed numbers, fully geocoded records, and accurate sample with filtered out business and non-working numbers. We have developed multi-level scale capacity and can provide sample at the Government Office Regions(GOR) level, NUTS3 Areas, and city level. The The NUTS3 Areas can be linked to socio-demographic data while the city level allows for a highly effective means to target smaller population samples.
